Book of 99 features a Wild Book symbol, but unlike most slots [https://bedavaslotoyna.com/](https://bedavaslotoyna.com/) where the Wild substitutes regular symbols, it is also the key to Free Spins in this game. By landing at least 3, Wilds Books will reward players with 10 Free Spins. Additionally, for every Wild that is landed, the meter fills up by one, and players receive Free Spins when the meter reaches 99. Bets in Book of 99 vary between C$/£0.10 and C$/£100. I love this slot machine game, with the record high RTP of 99%! and a bonus round similar to the one on the famous Book of Dead online slot, Book of 99 will surely be a player’s favourite. Of course, our slot reviews already include the information along with the RTP, how the slot works, and what features you can expect.
