Slot Summary

One chosen symbol can expand across the reels during Free Spins, turning the bonus into a search for repeated full-reel matches. Book of Clovers wraps that mechanic in Spinomenal's Irish fantasy setting, where the golden book serves as both Wild Symbol and Scatter Symbol. The familiar Book format is therefore defined less by its 10 paylines than by the symbol selected for expansion.

How It Plays

The regular game uses a 5x3 layout and 10 paylines. Winning combinations form from matching symbols, while the book substitutes as a Wild Symbol.

The book also functions as a Scatter Symbol, giving one symbol two jobs. That dual role keeps the base loop simple while directing attention toward Free Spins.

Theme & Atmosphere

Irish folklore supplies the identity through Clover, Leprechaun, Lucky, and Magic themes, with the golden book presented as the route toward a hidden pot.

Fantasy elements support the Book format without displacing it. The setting uses an Irish village, mythical guardians, and treasure imagery to explain why the central book matters.

Features & Win Potential

The book combines Wild Symbol and Scatter Symbol functions. It can substitute during regular wins, while a qualifying group also opens the Free Spins feature.

Expanding Symbols operate only after a symbol has been selected for Free Spins. An expansion occurs when it creates a new payline, and its result is counted separately.

Bonus & Free Spins

Landing 3 or more book symbols awards 10 Free Spins. Before those spins start, a wheel selects the ordinary symbol that receives the Expanding Symbols function.

The selected symbol can expand across its reel when doing so creates a win. Additional qualifying books retrigger the feature and award another 10 Free Spins.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (95.90%), with wins capped at its top multiplier (5,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
