Features Book of Sam is a five-reel, three-row slot from ELK Studios with 10 paylines and medium-high volatility. The game features a 94% RTP and bet sizes from 0.20 to 100, with a free demo version available for players who want to explore the rules before playing for real money.
The main mechanics centre on three character-based features. Wins on Sam place a book symbol that acts as both a wild and a bonus symbol, wins on Sandra trigger a respin with an increased multiplier, and wins on Maggie remove low-value symbols, the cat and Maggie before new symbols fall into place. A bonus round starts when three or more book symbols appear.
In the free spins feature, players receive eight spins with up to three expanding symbols, while a retrigger adds four more spins and one additional expanding symbol. The X-iter mode offers five game variants, including an option with a higher chance of reaching the bonus and a Super Bonus where all symbols expand.
