How the reels pay — quick, readable action

The layout is simple: five reels, 10 paylines, and one coin per line. Coin sizes range from $0.01 up to $10, so you can scale bets from tiny tester spins to serious runs without changing the feel of the game. Symbols include classic fruit icons like Cherries, Lemon, Plum, Orange and Watermelon, plus Bell, Single BAR, Seven, a Red Diamond, and the central Book Of Diamonds icon.

• Regular symbols form wins across the 10 paylines; the Red Diamond and the Book Of Diamonds are the ones to watch.
• The Book Of Diamonds doubles as the special icon that triggers the bonus sequence. It behaves like a scatter/wild hybrid and is central to unlocking free spins and extra mechanics.
• Games move at a clean clip: the interface highlights winning lines clearly, so you always know when a combo is working in your favor.

Bonus mechanics that boost payouts and make spins pop

This slot stacks three rewarding bonus ideas into one package:

• Free Spins Feature: Land the Book Of Diamonds scatters and you’ll activate 10 free spins. That’s where the game accelerates from steady to potentially big.
• Expanding Symbol during Free Spins: On entry to the free spins round, a single symbol may be chosen to expand and cover entire reels when it appears, converting partial wins into full-line payouts and often creating multiple big hits in one spin.
• Scatter Wild behavior: The Book symbol can also act like a wild, filling gaps and completing paylines that otherwise wouldn’t pay. When these scatter wilds combine with the expanding symbol, the result is frequent, satisfying pay jumps.

These mechanics are designed to chain off each other: scatters set up the free spins, free spins increase your chance to see expanding symbols, and the wild properties of the Book push payouts higher. The result is a concise feature loop that rewards both small bets and bolder plays.

Play smarter: betting and feature timing tips

Think in rounds, not single spins. With 10 paylines and one coin per line, focus on bet size more than line selection — the paylines are fixed, so your primary lever is coin value.

• Start low to get a feel for symbol frequency. The game’s features are generous enough that you’ll experience the Free Spins feature within a reasonable session when you test with smaller bets.
• When you hit a streak, consider raising the coin size gradually rather than jumping straight to max bet. That keeps bankroll pressure manageable while letting you capitalize on positive variance.
• Use free spins as your opportunity to press a bit more. Expanding symbols during the bonus round increase the potential ROI, so a modest uptick in bet size can pay off disproportionately.
• Watch volatility in real time: if wins come frequently but small, maintain steady stakes; if you hit longer dry spells, reduce coin size and preserve your session.

Above all, treat Book Of Diamonds like a short-session game: quick rounds, clear features, and the excitement of a potential payout cascade make it perfect for players who want action without a long grind.

Book Of Diamonds blends classic slot charm with modern bonus design. Whether you play for relaxed spins or aim for feature-driven wins, those 10 free spins and the expanding-symbol moments are where the big surprises live. Spin with intent, enjoy the visual hits, and see if a few well-timed bets can turn those diamonds into a standout payout.
