Book of 99 Slot Review

Book of 99 by Relax Gaming takes you on a Greek mythology adventure with a rewarding twist. This 5-reel, 10-payline slot stands out with its clever Collection Meter and Free Spins features. Your aim will be to get those Wild symbols that unlock the game's most rewarding elements.

The Wild symbol is your best mate here, subbing in for everything except the Free Spins Expanding symbol. Land 3 or more Wilds to trigger 10 Free Spins where one symbol expands across the reels, and it pays on every line no matter where it lands. As if that wasn't enough, collect 99 Wilds in the base game, and you'll trigger more spins based on your average bet.

With its sky-high RTP and powerful features, this game is too good to be ignored.
