Book of Big Wins
Gamdom has reported another eye-catching payout after a player landed a 655x multiplier on Book of 99 by Relax Gaming.
A single $80 spin produced a $52,440 win, shared by the casino on its X.com page.
The result stands out among Gamdom’s usual big-win announcements, which often feature titles from Pragmatic Play and Hacksaw Gaming.
This time, the spotlight shifts to Relax Gaming and one of its most mathematically generous creations.
Book of 99 - A Hidden Gem
At first glance, Book of 99 appears to follow the familiar “book of” formula. Yet the game offers two rare advantages: an exceptional 99% RTP and a Wild-collection mechanic that rewards consistent play.
Set against an ancient Greek backdrop, the slot features a 5×3 layout, 10 paylines, and high volatility. It offers a potential top win of 12,075x the stake but omits any bonus-buy shortcut—players must trigger free spins naturally.
Key Features at a Glance
| Feature | Description |
|---|---|
| Wild Symbol | The Book acts as both Wild and Scatter. Three or more trigger free spins. |
| Free Spins | 10 free spins are awarded, with one symbol chosen to expand across all paylines. |

| Volatility / RTP | High volatility with a standout 99.0% RTP. |
| Max Win | 12,075x stake. |
The expanding symbol mechanic remains the game’s main route to major wins, as seen in Gamdom’s latest highlight.
