Gamdom Casino pays out on another big win as one lucky player smashed a juicy 655x multiplier on Book of 99 to win $52,440.00.

Book of Big Wins

With so many ‘book of’ slots now available, it was inevitable that a big win would happen on one of these games. That honor now goes to Relax Gaming’s Book of 99.

Gamdom Casino shared news of this Book of 99 win on its X.com page. A bet of $80 led to a magnificent 655x multiplier, which produced a $52,440.00 payout.

Typically, Pragmatic Play and Hacksaw Gaming slots dominate these Gamdom big win articles, so it’s refreshing to see Relax Gaming grabbing the headlines on this occasion.

Book of 99 - A Hidden Gem

Book of 99 is an ancient Greece-themed slot by Relax Gaming. Based on the title, you would be forgiven for thinking this is just another ‘book of’ style slot, but this game has something few others do. That is a stunning RTP (Return to Player) of 99.0% and a unique Wild collection system that rewards active players with free spins once the meter is full.

Rated as highly volatile, Book of 99 has five reels and three rows. It boasts a modest 10 paylines and a potential maximum payout of 12,075x your bet. With no bonus buy features, players have to work their way through the base game until they trigger the free spins bonus round.

Slot Features

Wild Symbols: The Book of 99 is the Wild symbol. This substitutes all paying symbols to create winning paylines. Also, when three or more Wild symbols land on the reels together, it triggers the free spins feature.

Free Spins: Players are awarded 10 free spins. During this feature, a special expanding symbol is randomly chosen. When it expands, it can payout on all 10 winlines, which is when the Book of 99 big wins usually come.

Wild Collection: Every Wild symbol that lands on the reels in the base game increases the collection meter by one step. The meter is full after you’ve collected 99 Wilds. This triggers the free spins feature. As a note, the bet size is the average of the bet sizes you used when collecting the 99 Wilds.
