Book of Sam is a 5x3 slot with 10 paylines designed by ELK Studios that features the troll family. Through the Electric Treat feature, each of the three trolls provides unique base-game modifiers, and the same occurs more frequently during the bonus round. You receive up to three expanding symbols at the outset, with rewards of up to 10,000 times your wager.
You receive three distinct troll modifiers at random during all game stages, and they occur more frequently during the expanding symbols bonus round. Up to three symbols can expand immediately, with a maximum of five possible. The 10,000x multiplier is double the average for 'book of' slots, but the top-tier RTP of 94% is a deal-breaker for many players.
You need 2 to 5 matching premium symbols on a payline to win, and 5 of a kind triumphs pay between 10 and 500 times your wager. The Book symbol is both wild and scatter, and it substitutes for pay symbols to help complete winning combinations. If you win with nothing but wilds, you will receive the same payout as the top-tier Sam symbol.The Electric Treats feature can activate at any point in the game whenever one of the troll family symbols contributes to a victory of any kind:
When 3, 4, or 5 book scatters appear in view, the Bonus Round is triggered, and 8 free spins with 1, 2, or 3 expanding symbols are awarded. Which pay symbols are selected as expanding is completely at random, and these special symbols expand to create full-payline wins if sufficient instances fall anywhere in view (at least two premium symbols anywhere or three or more royals).
During the bonus round, landing three or more book scatter/wild symbols awards additional spins and one additional expanding symbol. You can obtain a maximum of five expanding symbols, and Sandra's multiplier remains active during all Electric Treat modifiers. Sam's electric treat is not active during regular free spins, but when it is, the book symbol becomes an expanding wild that helps fulfil expanding wins.
