Key Takeaways
| Data Label | Value |
|---|---|
| RTP | Book of the Dragon RTP is 96.21%, confirmed on the Felix Gaming official page and matched by CasinoLandia spec data; SlotCatalog confirms the game fingerprint but lists RTP as N/A on its English page. |
| Max Win | 5,000x total bet, per Felix Gaming and SlotCatalog. GB cash equivalent is up to £25,000 at the £5 game-cycle cap for 25+ players, or £10,000 at the £2 cap for 18-24 players. |
| Bet Range | Official developer range is EUR 0.10-50.00 per spin. GB online slots are capped at £5 for 25+ players and £2 for 18-24 players; no native GBP operator range was verified. |
| Volatility | High, with Felix Gaming rating it level 4 on its 5-point scale; some secondary coverage softens this to medium-high. |
| Grid / Ways | 5 reels, 3 rows, 10 fixed paylines, per Felix Gaming and SlotCatalog. |
| Bonus Trigger Rate | Not published by Felix Gaming, SlotCatalog, or any checked UK operator source. |
| Hit Frequency | Not published in allowed sources. |
| Series Status | Book-style dragon release under the official product title Book of Dragon Hold and Win; not the Spinomenal Book of Dragons or Apparat Book of Dragon title. |

| Best RTP Operator | Not verified. No UKGC-licensed operator page showed a public active RTP setting in the sweep. |
| Avoid If | Avoid if unpublished hit frequency, high volatility, or offshore-only distribution makes the game too opaque for the intended session. |
Book of the Dragon Quick Verdict
Book of the Dragon slot review begins with the essentials: this is Felix Gaming’s Book of Dragon Hold and Win, released on 21 July 2024, with a 96.21% RTP, 5,000x max win, high volatility level 4, a 5×3 layout, and 10 fixed paylines. Felix Gaming does not disclose a parent group on felixgaming.com; the site names Alea as its exclusive direct integrator and lists Anjouan Licensing Services Inc. as regulator. Data confidence is high for the core math and mechanics, and medium for market distribution because operator-side RTP panels could not be verified.
The verdict-shaping fact is the hybrid structure. This is not a plain Book of Ra-style clone: Felix Gaming combines classic randomly selected expanding-symbol free spins with a separate Hold and Win egg-respin feature. Felix Gaming is licensed in Anjouan (Comoros), not by the UKGC, so Book of the Dragon is carried only at offshore casinos and is not available at UKGC-licensed UK operators; UK readers should compare the mechanics with regulated Book-style alternatives such as Book of Ra slot review, Book of Shadows slot review, Eye of Horus slot review and Book of Oz slot review.
RTP, volatility, and bonus mechanics are subject to change. Verify current figures at the operator site before depositing.
Math Model
Felix Gaming publishes a 96.21% RTP for Book of Dragon Hold and Win, and CasinoLandia repeats the same 96.21% figure in its spec panel. SlotCatalog confirms the provider, 21.07.2024 release date, 5×3 layout, 10 paylines, EUR 0.10-50.00 bet range, and 5,000x max win, but its English page lists RTP and variance as N/A. Felix Gaming is therefore the controlling source for RTP and volatility, with SlotCatalog used for cross-checking the surrounding identity fingerprint.
Book of the Dragon RTP Detail
The published RTP is a single 96.21% value. We found no Felix Gaming public page evidence of operator-configurable RTP variants for this title, and no game IDs for lower RTP builds were visible in the public product data. Because SlotCatalog lists RTP as N/A on the page we checked, the Book of the Dragon RTP claim rests on Felix Gaming as primary source and CasinoLandia as secondary spec support, while SlotCatalog supports the same product identity rather than the RTP line itself.
Because Felix Gaming is Anjouan-licensed rather than UKGC-licensed, no UK operator active RTP setting exists to verify; the operator sweep is detailed in the Where to Play and verification sections below. Third-party demo aggregators may show the provider’s default demo configuration and should not be used as proof of a live real-money RTP.
Volatility in Practice
Felix Gaming rates the game at volatility level 4, which we are treating as high. That fits the structure: 10 fixed paylines keep the base game simple, but the main value routes sit behind 3+ BOOK symbols for free spins and 6+ EGG symbols for the Hold and Win bonus. Some secondary coverage describes the slot as medium-high, but the developer’s level 4 rating is the stronger source and is used throughout this review.
Compared with Book of Ra slot review, the volatility profile is familiar because the expanding symbol can reshape a free-spins round around one randomly selected icon. Compared with the Buffalo Power Hold and Win respin loop, the extra egg-respin layer gives Book of the Dragon more bonus variety, but not more public telemetry. No allowed source publishes the probability split between the two bonus routes.
Book of the Dragon Max Win
The Book of the Dragon max win is 5,000x total bet, confirmed by Felix Gaming and SlotCatalog. At the official EUR 0.10 minimum, that equals EUR 500 in developer-file terms. If a GBP operator ever mapped the same minimum to £0.10, the equivalent minimum-stake top prize would be £500, but no UKGC operator range was verified.
The developer-side EUR 50.00 maximum would produce a EUR 250,000 non-GB reference figure at 5,000x. That is not the GB headline. GB players at UKGC-licensed operators are limited to £5 per game cycle for customers aged 25+ and £2 for customers aged 18-24, so the GB maximum cash equivalent is £25,000 at the £5 cap, or £10,000 at the £2 cap.
Hit Frequency vs Bonus Trigger
Hit frequency and bonus trigger rate are separate metrics. Hit frequency measures how often any win lands, while bonus trigger rate measures how often the free spins or Hold and Win features start. Felix Gaming does not publish either number for Book of Dragon Hold and Win, SlotCatalog lists hit frequency as N/A, and no checked operator source exposed a trigger rate. Gaps between bonus events therefore vary, and session planning should be based on budget and time rather than expected bonus frequency.
Best RTP operators: none were independently verified. The highest available figure remains Felix Gaming’s 96.21% developer RTP, and there is no operator-configurable variant in the public product data.
Bonus Features
BOOK Wild and Scatter
The catch is that BOOK symbols have to carry two jobs, so they are powerful but not independently frequent in the public data. Felix Gaming states that the BOOK symbol acts as the special scatter route into free spins and also substitutes as a wild for regular payline wins.
Three or more BOOK symbols trigger the free-spins feature. This resolves a common source conflict: several secondary pages state 10 free spins, but Felix Gaming’s official page says 12 free spins, so 12 is the figure used in this review.
Free Spins and Expanding Symbol
Book of the Dragon free spins award 12 spins when 3+ BOOK symbols land, per Felix Gaming. Before the round starts, one regular symbol is selected at random as the special expanding symbol, and that symbol can expand to fill a full reel during the feature.
The limitation is randomness. The chosen expanding symbol can be a premium icon or a lower symbol, and no allowed source publishes the selection weighting. Felix Gaming also states that each further set of 3+ BOOK symbols awards another 12 free spins, so the round is retriggerable in 12-spin blocks. UK readers who want the same single-symbol expansion on a regulated release can compare the expanding-symbol round in Tome of Life.
Hold and Win Eggs
The Hold and Win bonus is the feature that separates this from a plain Book format. Felix Gaming says 6 or more EGG symbols in the base game trigger the feature, with GOLDEN EGG, SILVER EGG, BRONZE EGG and WOODEN EGG symbols involved.
CasinoLandia describes the round as a 3-respin collection feature where each new EGG symbol resets the respin count and remains on the grid. The public data confirms cash or multiplier-style egg values, but it does not publish tier probabilities, full-screen frequency, or the distribution of Gold, Silver, Bronze and Wooden egg outcomes.
Feature Buy Status
Felix Gaming’s official product page confirms that the game includes a BUY BONUS feature, but it does not publish the cost or the exact menu split in the public text we checked. Some secondary coverage reports a Buy Feature, and unverified aggregator data mentions roughly 50x-65x bet, but that cost is not treated as confirmed because it is not on the official page.
This matters for comparison because feature-buy pricing changes the effective entry cost into the bonus path. The clean verified statement is narrower: a Buy Bonus exists, the public official page does not publish the price, and SpinHunter is not using unconfirmed cost figures as fact.
Feature Buy Options
The decision space is thin in the public data. Felix Gaming confirms a Buy Bonus, while CasinoLandia confirms a direct-purchase feature, but neither source gives a developer-verified price table for this exact build. That means there is no public expected-value comparison between waiting for 3+ BOOK symbols, waiting for 6+ EGG symbols, or buying entry where the option is present.
For UK-facing comparison, feature buys should be treated as a non-core mechanic rather than the main reason to assess the slot. Players looking for a no-deposit free-spin promotion surface can use that route on UKGC-licensed alternatives to observe Book-style bonus rounds without relying on an unverified Felix Gaming buy-cost claim.
Base Game
The base game uses 5 reels, 3 rows and 10 fixed paylines, per Felix Gaming and SlotCatalog. Wins form from the leftmost reels, while the Felix Gaming description adds a special detail: at least two matching DRAGON symbols can also form a win. Readers drawn to the dragon dressing rather than the Book mechanic can look at the UK-available dragon theme of Smoking Dragon. The official bet range is EUR 0.10-50.00, and any GBP range should be treated as a currency adaptation rather than a native developer listing.
Book of the Dragon mobile compatibility is HTML5-based, with SlotCatalog listing JS and HTML5 technology and CasinoLandia listing mobile, desktop and tablet support. That supports play on iOS and Android browsers where an operator offers the game, although active RTP and stake settings still depend on the actual operator implementation.
Wild – The BOOK symbol substitutes for regular symbols to help form payline wins. Felix Gaming describes it as one of the special symbols, and CasinoLandia confirms it acts as a Wild in addition to its scatter role.
Scatter – The same BOOK symbol triggers the free-spins bonus when 3 or more appear. Felix Gaming confirms that 3+ BOOK symbols award 12 free spins, with a random expanding symbol selected before the round starts.
EGG Symbols – GOLDEN EGG, SILVER EGG, BRONZE EGG and WOODEN EGG symbols are tied to the Hold and Win feature. Felix Gaming confirms 6+ EGG symbols trigger the feature, while CasinoLandia describes the 3-respin reset-on-hit collection loop.
Published Symbol Values – Felix Gaming’s public product page lists symbol types but does not publish a full text paytable by symbol. CasinoLandia exposes image-indexed numeric rows, but because the scraped page does not reliably pair every value with a named symbol, this review does not map those numbers into a formal paytable.
Pros & Cons
| Pros | Cons |
|---|---|
| Felix Gaming publishes a 96.21% RTP, which is stronger than many classic Book-format slots in the SpinHunter catalogue. | SlotCatalog lists RTP as N/A on the checked English page, so RTP confirmation depends on Felix Gaming plus one secondary spec source rather than two full database confirmations. |
| The 5,000x ceiling is developer-confirmed and gives the game the same multiplier target as Book of Ra slot review and Eye of Horus slot review. | The 5,000x ceiling is below Book of Shadows slot review at 10,670x and below Floating Dragon slot review at about 6,500x. |
| The hybrid design combines expanding-symbol free spins with a separate Hold and Win egg-respin feature, per Felix Gaming and CasinoLandia. | No allowed source publishes hit frequency, free-spins trigger rate, Hold and Win trigger rate, or egg-tier probabilities. |
| The official free-spins count is clear: Felix Gaming states 12 free spins on 3+ BOOK symbols, resolving the secondary-source 10-spin mismatch. | The Buy Bonus cost is not published on the official Felix Gaming page, so any 50x-65x cost claim remains unverified. |
| The BOOK symbol has useful dual behaviour as both wild and scatter, which keeps the theme mechanically coherent. | The randomly selected expanding symbol can land on lower-value icons, and no allowed source publishes the selection weighting. |
Where to Play Book of the Dragon
Felix Gaming is licensed in Anjouan (Comoros), not by the UKGC, so Book of the Dragon is carried only at offshore casinos and is not available at UKGC-licensed UK operators. We confirmed this with a public operator sweep; Sky Vegas, Paddy Power, Betfair Casino, BetMGM UK, William Hill, bet365, LeoVegas, Mr Q, PlayOJO, 888 Casino, Buzz Casino, Coral, Ladbrokes and Virgin Games returned no visible pre-login product page or active RTP panel. For regulated alternatives, the closest SpinHunter catalogue routes are Book of Ra slot review, Book of Shadows slot review, Eye of Horus slot review, the fantasy-theme Book of Oz and Floating Dragon slot review. A Book of the Dragon free demo is visible through Felix Gaming and SlotCatalog; third-party demo aggregators may show the provider’s default demo configuration and should not be used as proof of an operator’s live real-money RTP. Low-stake comparison research can also use low-deposit casino options or free spins no deposit offers attached to UKGC-licensed alternatives.
Similar Slots
The closest comparisons split into two groups: classic Book-style expanding-symbol slots and Hold and Win collection slots with similar 5,000x-ish ceilings.
| Slot | Developer | RTP | Max Win | Volatility | Key Difference |
|---|---|---|---|---|---|
| Book of Ra slot review | Novomatic | About 95.10% | 5,000x | High | Closest classic Book template with 5×3 reels, 10 lines and one expanding special symbol. |
| Book of Shadows slot review | Nolimit City | 96.08% | 10,670x | High | Darker modern Book mechanic with a higher ceiling and sharper variance profile. |
| Eye of Horus slot review | Merkur Gaming | About 96.31% | About 5,000x | Medium-high | Near-like-for-like Egyptian expanding-symbol option with a slightly higher published RTP. |
| Book of Oz slot review | Microgaming | About 96.31% | About 5,000x | Medium-high | Book clone with a lighter fantasy theme and a comparable ceiling. |
| Floating Dragon slot review | Pragmatic Play | About 96.50% | About 6,500x | High | Dragon-themed money-collect alternative with a higher published ceiling. |
For the closest mechanical match, Book of Ra slot review remains the template comparison. It has the same basic 5×3, 10-line Book rhythm, but it lacks the added egg-based Hold and Win route that Felix Gaming adds here.
For ceiling hunters, Book of Shadows slot review is the stronger comparison because 10,670x materially exceeds 5,000x. The trade-off is that Nolimit City volatility can feel more concentrated around extreme outcomes.
For theme-led players, Floating Dragon is the cleaner UK-playable dragon alternative in the SpinHunter catalogue. It does not copy the Book free-spins mechanic, but it fits the dragon-and-collect preference better than another Egyptian Book reskin.
Player Sentiment & Reviews
SpinHunter editorial rating: 3.4/5. The one-line verdict is that Book of the Dragon has a stronger mechanic mix than a routine Book clone, but public telemetry gaps and limited regulated-market visibility hold it back.
| Theme | Observation |
|---|---|
| Mechanic reception | Industry coverage focuses on the hybrid structure: 12-spin expanding-symbol free spins plus a separate 6+ EGG Hold and Win feature. The recurring positive signal is that the slot avoids being only another single-feature Book game. |
| Visual and atmospheric response | Publisher material and industry coverage position the game around dragons, treasure, books, potions and eggs. The visual response is strongest for players who like fantasy Book themes rather than strict Egyptian explorer styling. |
| Streamer and clip pattern | Accessible streamer coverage is thin compared with larger Book franchises. No consistent public clip pattern was found around max-win attempts, full-screen eggs, or repeated expanding-symbol bonuses. |
| Community pattern | Community discussion appears scattered rather than concentrated around one dominant forum thread. The recurring praise is mechanic variety; the recurring complaint is the absence of published trigger rates and egg-tier probabilities. |
| Comparator pairing | Industry coverage naturally pairs the game with Book of Ra slot review for the expanding-symbol route and Buffalo Power Hold and Win slot review for the respin-and-collect route. Floating Dragon slot review is the theme-adjacent comparison. |
| Coverage gap | The key missing data remains hit frequency, free-spins trigger rate, Hold and Win trigger rate, Buy Bonus cost and egg-tier distribution. Those gaps matter more here because the slot has two bonus routes rather than one. |
The reception pattern is therefore mechanic-positive but data-limited. Players who already like Book-style expanding symbols have a clear reason to notice the game, because the Hold and Win layer gives the base game a second feature identity.
The complaint pattern is not about the 96.21% RTP or the 5,000x ceiling, both of which are clear on Felix Gaming’s page. It is about the missing pacing data. Without published trigger rates, no review can fairly model how often the two bonus paths should appear.
Where Book of the Dragon Sits in Felix Gaming’s Lineup
Felix Gaming is an Anjouan-licensed slot supplier with more than 70 games launched since 2017, and its catalogue leans heavily on classic reels, Book mechanics, Hold and Win formats, and multiplier-led bonus structures.
| Slot | RTP | Max Win | Volatility | Position vs Book of the Dragon |
|---|---|---|---|---|
| Book of Dragon Hold and Win | 96.21% | 5,000x | Level 4 | Subject slot with Book plus Hold and Win hybrid structure. |
| Book of Anunnaki | 95.87% | 5,000x | Level 4 | Lower RTP, same ceiling, purer Book free-spins format. |
| It’s a Joker | 96.98% | 700x | Level 4 | Higher RTP, much lower max win, simpler classic-slot structure. |
| Joker Qwin Hold And Win | 96.31% / 94.73% / 92.76% | 5,000x | Level 5 | Slightly higher top RTP, same ceiling, sharper Hold and Win profile. |
| Wolf Gone Wild Hold And Win | 96.40% / 94.68% / 92.55% | 4,000x | Level 3 | Higher top RTP, lower ceiling, softer volatility rating. |
| Jack The Winner | 96.84% | 7,680x | Level 4 | Higher RTP and ceiling, but a different ways-to-win bonus structure. |
On RTP, Book of the Dragon sits in the middle of the sampled Felix Gaming catalogue. It is above Book of Anunnaki at 95.87%, below It’s a Joker at 96.98%, and below Jack The Winner at 96.84% per Felix Gaming’s public pages.
On ceiling, it is a proper mid-to-high Felix Gaming release rather than a low-ceiling classic. The 5,000x cap matches Book of Anunnaki and Joker Qwin Hold And Win, beats Wolf Gone Wild Hold And Win at 4,000x, but sits below Jack The Winner at 7,680x.
Mechanically, it is one of the cleaner hybrid entries because both feature paths fit the theme: BOOK symbols open the explorer-style free spins, while EGG symbols drive the dragon treasure Hold and Win round. This is Felix Gaming’s mid-tier fantasy Book release with a stronger bonus mix than its pure Book sibling.
Is Book of the Dragon Worth Playing?
Book of the Dragon is worth researching for players who want a Book-style free-spins slot with a second Hold and Win bonus path, but it is not a clean fit for anyone who needs verified UK operator availability, published trigger rates, or a transparent feature-buy price.
High-roller bankroll grinders: the 5,000x ceiling is the main ceiling marker, not a GB high-stake route. Under GB cap math, that same multiplier equals £25,000 at the £5 cap for 25+ players or £10,000 at the £2 cap for 18-24 players, while the developer-side EUR 50.00 maximum is non-GB reference context only. Casual session players: the official EUR 0.10 minimum gives a low entry point in developer-file terms, and the equivalent 5,000x result would be 500 units at the minimum; GB cap context remains £25,000 at £5 and £10,000 at £2, while low-deposit casino options are more relevant for regulated alternatives. Bonus hunters and feature buy players: the feature-buy angle is weakly documented because Felix Gaming confirms the Buy Bonus but does not publish cost, while free spins no deposit offers on UKGC-licensed alternatives offer a cleaner way to sample Book-style bonus mechanics.
Confirmed strengths: Felix Gaming confirms the 96.21% RTP, 5,000x max win, 10 fixed paylines, level 4 volatility, 12 free spins on 3+ BOOK symbols, and 6+ EGG Hold and Win trigger. CasinoLandia supports the 96.21% RTP, high volatility, HTML5 compatibility, mobile availability and 3-respin reset-on-hit Hold and Win description.
Confirmed weaknesses: Felix Gaming does not publish hit frequency, bonus trigger rate, egg-tier probabilities, feature-buy cost, or win probabilities for 100x, 1,000x and max-win thresholds. SlotCatalog lists RTP and variance as N/A on the checked English page, so it is not a clean second-source RTP confirmation even though it confirms the product fingerprint.
The competitive picture is clear. Book of Ra slot review is the closest classic Book reference, the higher-ceiling modern Book alternative is Book of Shadows, Eye of Horus slot review is the most direct expanding-symbol peer by RTP band, and Floating Dragon slot review is the stronger dragon-themed regulated comparison.
Alternatives by Player Goal
If you want a higher published RTP: Floating Dragon slot review is the cleaner dragon-themed alternative, with SpinHunter catalogue data placing it at about 96.50% RTP compared with Book of the Dragon at 96.21%.
If you want a higher ceiling: Book of Shadows slot review is the obvious Book-style upgrade path because its 10,670x max win is materially above the 5,000x cap on Felix Gaming’s title.
If you want lower volatility: the more balanced Book-style comparison is Eye of Horus in the SpinHunter catalogue, with a similar 5,000x-ish ceiling and less severe public positioning than many modern high-volatility Book releases.
If you want the same theme: Floating Dragon slot review keeps the dragon focus and money-collect style, even though it does not use the same BOOK wild/scatter route.
If you want the same core mechanic: Book of Ra slot review remains the purest same-mechanic alternative because the 5×3, 10-line expanding-symbol free-spins format is the genre template that Book of the Dragon builds on. For the second mechanic, the respin-and-collect loop is matched by the hold-and-spin collection in Gold Party 2 After Hours.
How This Review Was Verified
Sources were checked in June 2026. The primary developer source was felixgaming.com/games/book-of-dragon/, with felixgaming.com used for company, integrator and licensing context. The UK operator sweep checked Sky Vegas, Paddy Power, Betfair Casino, BetMGM UK, William Hill, bet365, LeoVegas, Mr Q, PlayOJO, 888 Casino, Buzz Casino, Coral, Ladbrokes and Virgin Games for visible pre-login product pages, active RTP panels, licence footers, stake ranges and jackpot overlays; none showed a public Book of the Dragon listing. Secondary spec checks used slotcatalog.com and CasinoLandia, with SlotCatalog confirming release date, max win, layout, stake range and HTML5/JS technology, while listing RTP as N/A on the checked page. Hit frequency, bonus trigger rate, feature-buy cost, egg-tier probabilities and win-probability thresholds were not independently verified. Players should treat any figure here as point-in-time and confirm the active configuration in the operator help panel before depositing real money. RTP, volatility, stake limits, and feature availability are subject to operator-side updates that this review cannot pre-empt.
Responsible Gambling
High-volatility slots can create uneven outcomes, especially when key trigger rates are unpublished. Set a fixed budget and time limit before starting, use deposit limits where available, and stop when the planned limit is reached rather than chasing a specific feature.
RTP is a long-run model, not a session forecast. Using the 96.21% RTP, the long-run loss rate is 3.79%. A £100 bankroll at the GB £5 cap gives £100 divided by (£5 x 0.0379), or about 528 theoretical spins before expected-loss exhaustion; at the £2 cap for 18-24 players, £100 divided by (£2 x 0.0379) gives about 1,319 theoretical spins. Real sessions can finish much sooner or last longer because volatility dominates short-term results.
