Book of Time is an online slots game created by Hacksaw Gaming with a theoretical return to player (RTP) of 96.13%. This game is a time-themed 5×4 paylines slot with both a classic book mechanic bonus game and a spreading wild multiplier bonus game. The max win is 10,000 times your bet.
The lower-paying symbols consist of the classic royal symbols: 10, J, Q, K, and A. Five-of-a-kind with these will pay 5x-15x the bet. The higher-paying symbols are made up of a Wand, Hat, Knife, Snake, and Mouse. A full line of 5 with these pays 50x-250x the bet. Compared to most competitors, Hacksaw offers some crazy line wins, as you notice. Landing 3 or more Book symbols triggers one of the Bonus features, and they also act as Wild symbols to enable more winning combinations. Lastly, we have the Clock Man Scatter symbol, which you also need 3 of to trigger the other Bonus feature.
Getting 3 bonus hours in the main game triggers a round, in which there will be 10 free spins. Above reels 2, 3, and 4, this game displays a clock showing a different time on each spin. When a Clock Activator symbol lands on reels 2, 3, or 4, the Multiplier Clock Wilds spread from top to bottom, replacing all symbols until reaching the Clock Activator, which they also replace. The value of the multiplier is determined by the time displayed on the clock, which can be from 2x to 12x.
