The Slotfather: Book Of Wins - Hold & Win
The Slotfather Book of Wins Hold Win slot by BetSoft at Red Dog Casino brings the legendary crime boss and his crew back for their most feature-packed chapter yet. Released June 27, 2024, this video slot runs on a 5x3 grid with 10 fixed paylines, two full bonus features — a Hold & Win respin round and a Book of Wins free spins mode with expanding symbols — and a max win of 11,878x the stake. Very high volatility, 96.60% RTP, and a 24.68% hit rate that tells you exactly what kind of game this is: lean base game, explosive bonus rounds.
If you want a slot online with genuine franchise personality, two mechanically distinct bonus modes, and a max win that justifies the variance, The Slotfather: Book of Wins delivers. Here's everything you need before your first spin with the Don.
The Slotfather: Book of Wins Online Slot Review
The Slotfather franchise has been one of BetSoft's most enduring — the original Slotfather launched in their Slots3 era and built a reputation for cinematic mob aesthetics and strong bonus mechanics. Book of Wins is the latest entry, and it shows BetSoft operating at their current production peak. The visual design is polished: a 1960s Italian city backdrop, gritty nighttime streets, and fully animated character symbols. The Slotfather himself stands to the left of the reels, and crew members Frankie Knuckles and Fat Tony appear as two of the highest-paying symbols.
- Mafia-themed design with immersive atmosphere
- Combination of Book and Hold & Win mechanics
- High win potential through bonus features
- Engaging gameplay with expanding symbols
- Appeals to experienced and adventurous players
- High volatility may not suit beginners
- Bonus rounds can be infrequent
- No progressive jackpot
The core structure is a conventional 5x3, 10 fixed payline slot game — wins from left to right, 3+ matching symbols required. Nothing unusual there. What elevates the game is the dual bonus structure: the Book of Wins mechanic grafted onto a free spins round, and the Hold & Win respin feature built around accumulating Bonus symbols. Both are well-implemented and mechanically distinct from each other, which means the game has two completely different session peaks rather than one.
The 24.68% hit rate is the honest reality of very high volatility — roughly one win every four spins in the base game. Sessions between bonus triggers can feel lean. That's the deal with this volatility tier, and it's the correct trade-off given that the Hold & Win feature's Bonus symbols carry values up to 2,000x the bet and the max win sits at 11,878x. Players who understand that this game exists primarily to deliver bonus round payouts — not steady base game returns — will get the most from it.
Main Instructions
Getting started is fast. Here's the full sequence:
- Set your bet between $0.20 and $40.00 per spin using the controls at the bottom of the screen
- Press Spin or activate AutoPlay for hands-free sessions
- Wins form when 3 or more matching symbols land on adjacent reels from left to right on an active payline
- The Book symbol acts as both Wild and Scatter simultaneously — it substitutes for all regular symbols and triggers Free Spins when 3+ land anywhere
- Land 6 or more Bonus (coin) symbols anywhere on the reels to trigger the Hold & Win Feature
- Use the Buy Feature icon to purchase direct access to either bonus — check the current cost before purchasing
- During Free Spins: the Book of Wins mechanic randomly selects one regular symbol; that symbol expands to cover entire reels throughout the round
- During Hold & Win: 3 respins awarded; each new Bonus symbol sticks in place and resets the count to 3; filling the screen wins the maximum prize
Slot Features
The online casino feature set has four distinct components, each serving a different part of the win structure:
- Wild / Scatter Book Symbol — dual function: acts as Wild (substitutes for all regular symbols) and as Scatter (triggers Free Spins when 3+ land anywhere); landing 5 Book symbols on a payline pays 500x the bet independently
- Free Spins with Book of Wins — 3 Scatters: 10 free spins; 4 Scatters: 15 spins; 5 Scatters: 20 spins; on trigger, one regular symbol is randomly selected as the Book of Wins symbol; that symbol expands to fill any reel it lands on throughout the entire free spins round; all winning combinations involving expanded symbols are paid; the expanding mechanic significantly boosts win potential per spin
- Hold & Win Feature — triggered by 6 or more Bonus symbols anywhere on the reels; 3 respins awarded; all triggered Bonus symbols lock (stick) in their positions; the respin counter resets to 3 each time a new Bonus symbol lands; round ends when the counter reaches zero; Bonus symbols carry individual coin values printed on them — up to 2,000x the bet each; filling the entire screen with Bonus symbols wins the Grand Prize
- Bonus Symbol Values — the individual Bonus coins carry different values displayed on them; higher-value coins appearing late in a Hold & Win sequence (after most positions are locked) can significantly boost the round total
- Feature Buy — purchase direct access to either the Free Spins or Hold & Win feature at a cost displayed on screen; price scales with your current bet size
Boss Tip: Land Book symbols to trigger free spins and unlock powerful expanding wins.
Slot Setup and Betting Options
The Slotfather: Book of Wins runs on a 5x3 reel grid with 10 fixed paylines. All 10 lines are always active — there are no payline selection options. Wins require 3 or more matching symbols starting from the leftmost reel on an active payline.
The bet range of $0.20 to $40.00 per spin is practical for the very high volatility math. At $40.00 maximum, the 11,878x max win translates to a $475,120 theoretical maximum single-session payout from a single triggered Hold & Win sequence. Most players operate in the $0.50–$5.00 range for bankroll sustainability at this volatility tier.

The Slotfather: Book of Wins Bonus and Free Spins
Two bonus features, mechanically distinct. Understanding what each one does — and which produces the bigger single-session peaks — is essential for managing expectations at very high volatility.
Free Spins with Book of Wins:
- Trigger: 3, 4, or 5 Book Wild/Scatter symbols anywhere on the reels
- Spin awards: 3 Scatters = 10 spins; 4 Scatters = 15 spins; 5 Scatters = 20 spins
- On trigger, the game randomly selects one regular symbol as the Book of Wins symbol
- Whenever that chosen symbol appears on any reel during the free spins round, it expands to fill the entire reel vertically (3 positions)
- The expanded symbol substitutes across all paylines for that reel, significantly increasing win probability per spin
- The expanding mechanic applies throughout the entire free spins round — not just on individual spins
- Higher-value symbols (Slotfather, crew members) being selected as the Book of Wins symbol produce the biggest returns
- The Book Wild continues to substitute normally during free spins
Hold & Win Feature:
- Trigger: 6 or more Bonus (coin) symbols land anywhere on the 5x3 grid in a single spin
- 3 respins awarded; all triggered Bonus symbols lock in their current positions
- Each respin: any new Bonus symbols that land also lock and stick; the respin counter resets to 3
- Round ends when the counter reaches zero without a new Bonus symbol landing
- Bonus coins carry individual printed values — the total prize is the sum of all locked Bonus symbol values at the end of the feature
- Higher-value coins (up to 2,000x per coin) appearing mid-round can dramatically increase the total
- Filling all 15 grid positions with Bonus symbols wins the Grand Prize — the maximum payout achievable within the Hold & Win round
- The more positions locked early in the round, the higher the probability of continued respin resets and larger final totals
The Hold & Win feature is where the 11,878x max win lives. A Grand Prize fill — all 15 positions locked with high-value Bonus coins — is extremely rare but structurally defined by the mechanic. The free spins round with a high-value expanding symbol produces more consistent per-round returns than the Hold & Win, which has a wider boom-or-bust spread.
At Red Dog Casino, the welcome bonus of up to 225% on the first deposit is particularly valuable for very high volatility games like this — extended bankroll means more spins to reach either trigger condition (6+ Bonus symbols or 3+ Scatters). Check the online casino promotions tab after registration for no deposit offers applicable to BetSoft titles.
Family Tip: Use the Hold & Win feature to lock high-value symbols and build massive payouts.
Software Provider
BetSoft has been building casino games since 2006, and The Slotfather franchise represents one of their longest-running narrative series — from the original Slots3 era entry through to Book of Wins in 2024. That continuity shows in the production quality: the character animations, the 1960s Italian city aesthetic, and the crime-drama atmosphere are more developed than most one-off themed slots because BetSoft has been refining this world across multiple releases.
What defines BetSoft as a developer:
- Founded 2006 — nearly two decades of certified casino game development
- The Slotfather series is BetSoft's most recognizable long-form franchise — Book of Wins is the latest chapter
- Full format range: classic Slots3 (Barbary Coast), paying-both-ways (Boomanji), Hold & Win (Book of Wins), cluster pays (Miles Bellhouse), cascade slots (Treasures of Cleopatra)
- HTML5-first on all modern releases — full desktop and mobile compatibility without downloads
- Feature Buy implemented across their modern catalog — allows direct access to bonus rounds for players who prefer not to wait for organic triggers
- Fully licensed and independently audited for RTP accuracy and fairness across regulated markets
- Crypto-compatible at supported casinos — Bitcoin and digital currencies work with BetSoft's full catalog at Red Dog Casino
BetSoft's recent Hold & Win entries — Heist: Bank Rush Hold & Win, Take the Vault: Hold & Win, and now Book of Wins — form a coherent sub-series within their portfolio. Players who enjoy this game's dual-feature structure will find consistent quality across the other Hold & Win titles in the catalog.
The Slotfather: Book of Wins RTP, Volatility, and Max Win
The 96.60% RTP is above the industry average, which is notable for a very high volatility title — typically the two trade off against each other. BetSoft has maintained competitive math here while concentrating it in the bonus rounds rather than distributing it across base game spins.
Very high volatility at 24.68% hit rate defines the session experience: roughly one win per four spins in the base game, with most of those wins being modest. The game's expected return is strongly weighted toward the Hold & Win and Free Spins features. This is not a slot where the base game sustains you — it's a game where you're managing bankroll between feature events.
The 11,878x max win is among the highest published ceilings in BetSoft's current catalog. It requires a Hold & Win sequence where multiple high-value Bonus coins (approaching 2,000x each) fill the grid. The path to that number is structurally defined — not a theoretical ceiling artificially inflated by an impossible combination — but it requires multiple favorable Bonus coin values coinciding in a single Hold & Win round.

| Hit Rate | 24.68% |
| Max Win | 11,878x stake |

Verdict & Game Recommendations
The Slotfather: Book of Wins is BetSoft's strongest dual-feature slot in the current catalog. Two mechanically distinct bonus modes — the Hold & Win with accumulating sticky coins and the Book of Wins free spins with expanding symbols — mean the game has two completely different session peaks rather than one recycled trigger. The franchise identity adds genuine personality that most themed online slots lack: these aren't generic crime symbols, they're characters from a story BetSoft has been telling across multiple releases.
The very high volatility and 24.68% hit rate are not for everyone. Players who expect the base game to sustain them will find this frustrating. Players who understand that very high volatility games exist to deliver bonus round payouts — and who have the session budget to reach those bonus rounds repeatedly — will find the 11,878x ceiling and the dual feature structure genuinely compelling. Use the demo mode to experience both bonus types before committing real money to understand which feature rhythm suits your playing style.
Three games to try next at Red Dog Casino:
- Golden Pride (BGaming)
A 243-ways medieval slot with a single escalating Respin multiplier (up to 1,024x) and a 15,360x max win. Medium-high rather than very high volatility — for players who want high max win potential with a more accessible feature frequency. The Respin multiplier's doubling progression has a similar 'building anticipation' feel to the Hold & Win respin reset mechanic in Book of Wins.
- Treasures of Cleopatra (BetSoft)
Also by BetSoft — a 6x5 cascade slot with 96.62% RTP and accumulating multipliers up to 500x in free spins, with a 10,101x max win. High rather than very high volatility. For players who enjoy BetSoft's production quality and want a game where the free spins round produces the big payouts — same studio approach, different mechanic execution.
- Clash of the Giants (SpadeGaming)
A 6-reel cascade slot game with Kong multipliers accumulating during free games and a 10,000x max win. Medium volatility with a 96.85% RTP — significantly more accessible hit rate than Book of Wins. For players who want the sense of multipliers building across a bonus round without the very high variance floor, Clash of the Giants is the lower-risk equivalent.
Don’s Tip: Play smart and control your bets—the biggest wins come to those who stay patient.
FAQ
What's the max payout on The Slotfather: Book of Wins slot?
The maximum payout is 11,878x your stake. This is achieved within the Hold & Win feature when multiple high-value Bonus coin symbols (each carrying up to 2,000x the bet) fill the grid, with the respin counter resetting on each new coin. At the maximum bet of $40, this translates to a theoretical maximum payout of $475,120.
Can I win real cash if I play The Slotfather: Book of Wins?
Yes. Play The Slotfather Book of Wins for real money at Red Dog Casino and all wins — base game payouts, Book of Wins free spins, and Hold & Win feature totals — are credited as cash to your balance and fully withdrawable. BetSoft's certified RNG ensures every spin outcome is independently verified.
How many paylines are there in The Slotfather: Book of Wins slot?
The Slotfather: Book of Wins has 10 fixed paylines. All 10 are always active — there are no paylines to adjust. Wins form when 3 or more matching symbols land on adjacent reels from left to right on an active payline. The Book Wild/Scatter pays from any position regardless of payline.
Can I win real money playing The Slotfather: Book of Wins slots?
Absolutely. The Slotfather Book of Wins online at Red Dog Casino supports full real-money play with a 96.60% RTP. The very high volatility means the 11,878x max win and large Hold & Win payouts are the primary return drivers — all of which pay real cash credited to your account.
Can I play The Slotfather: Book of Wins slots with no deposit?
Red Dog Casino offers no deposit bonus for eligible new players after registration. Check the promotions tab for current availability on BetSoft titles. The demo version of The Slotfather: Book of Wins is available to experience both bonus features — the Hold & Win and the Book of Wins free spins — without any deposit.

No download required. The game is built in HTML5 and runs in your browser on desktop and mobile. Open the game at Red Dog Casino and start playing immediately without installation.
How does the bonus round work?
The Slotfather: Book of Wins has two separate bonus features. The free spins round triggers when 3 or more Book Wild/Scatter symbols land anywhere — 10, 15, or 20 spins depending on scatter count. Before the round begins, a random regular symbol is selected as the Book of Wins symbol; that symbol expands to fill entire reels whenever it lands during the free spins. The Hold & Win feature triggers when 6 or more Bonus coin symbols land anywhere on the grid — 3 respins awarded, all Bonus coins lock in place, and the counter resets to 3 each time a new coin lands. The feature ends when the respin counter hits zero; total prize equals the sum of all locked Bonus coin values. Both features can also be accessed directly via the bonus Buy Feature option.
