Book of Sevens™

Book of Sevens™ by Crucible Gaming is a classic-style slot with 3x3 reels and 5 paylines. The game uses a low-volatility model and an RTP of 96.18%, with bet sizes ranging from 0.05 to 50. Burning 7 symbols act as wilds, helping complete winning combinations on the main reels.

Landing three bonus symbols triggers a feature with 5 free spins. In the bonus round, a special gold symbol is selected; when it appears on a spin, it expands to cover the full reel. There is also a chance to retrigger the free spins bonus, extending the feature. A Spik Streak Bonus can also activate randomly in the base game, locking one symbol and respinning the rest until a win is formed.

The demo version is available to play for free, which lets users test the slot mechanics and bonus features before playing for real money. The game also includes Bonus Play, allowing direct entry into the bonus feature for an additional stake.
