Relax Gaming’s latest archeological slot release, developed in collaboration with CasinoGrounds, sees players sneak into an ancient tomb in Book of Power.


Out now




Book of Power is a 5×3 reel slot with 10-paylines and a maximum win of up to x15,000 the player’s bet.




96.11 per cent


Low value symbols are depicted as the high-end of a deck of cards, from 10 through to Ace. These symbols can offer between x0.5 and x15 the player’s stake, depending on the amount of matching combinations that land on a single spin. 

Pyramids, temples, pharaohs and archeologists represent the high value symbols, offering between x0.5 and x500 the player’s preferred bet. 

Two wild scatters are available, coming in the form of blue standard scatters and red power scatter books. These wilds substitute for all symbols other than the special expanding symbols in the free spins game mode. 

Landing three, four or five blue book symbols on the same spin will trigger 10, 15 or 20 free spins, respectively.  

If players land three or more book symbols on the same spin, and one of them is a red power book, the power free spins game mode will be activated.


During the free spins feature, one paytable symbol is chosen to be enhanced for the duration of the game mode. Throughout the game mode, this symbol will expand to cover the reels that they land in, increasing each spin’s win potential. 

If players land two or more scatters on the same spin in this feature, an additional five spins will be awarded as well as another randomly chosen enhanced symbol. If the chosen symbol is the same as the previously chosen symbol, it will apply a x2 multiplier to all wins formed with said symbol. 

During the power free spins game mode, the chosen symbol can payout from paylines without actually achieving the payline formation, paying out depending on how many symbols contribute to the combination. 

Landing a power book symbol on reels two, three or four will turn those reels golden, making the chosen symbol appear on that reel in every spin. 

Players can activate the power bet mode by doubling each bet size in order to receive an increased 70 per cent chance of triggering the bonus features. 

Furthermore, players can buy access to the free spins feature for the price of x100 the player’s stake or the power free spins for x200. 


Shelley Hannah, Director of Casino Products at Relax Gaming, stated: “After a wonderful experience collaborating with CasinoGrounds on previous releases, and incorporating feedback from players, we are thrilled with Book of Power.

“A multitude of exciting new features and excellent visuals will ensure that players are not going to forget their quest to obtain the Book of Power anytime soon.”
