Relax Gaming's 99% RTP book pokie with collectable free spins
A collection bar fills up as you play, handing out bonuses along the way rather than making you wait for one big trigger.
Activating free spins drops you into a bonus round where symbols can expand across the reels, opening up extra ways to win.
Book of 99 carries a multiplier that can climb as high as 12,075x, giving the high-volatility reels real top-end potential.
Adjust your bet using the control panel — the paytable updates dynamically to show the exact win values for your current stake.
Relax Gaming hosts a free version of the game directly on its site — scroll to the bottom of the game page and click 'Try Game' to load it.
Hit spin and keep an eye on the collection bar on the left of the screen as it builds toward bonus payouts.
Book of 99 spreads its bonus value across two connected mechanics rather than relying on one big trigger: a collection bar on the left of the screen fills as you play and hands out rewards along the way, while landing enough of the right symbols drops you into a free spins round where expanding symbols take over the reels. Paired with a 99% RTP and a multiplier ceiling north of 12,000x, it's the combination that gives the pokie its reputation as one of the more generous ancient-Greek-themed releases around.
Ninety-nine per cent. That’s the return-to-player figure stamped on Book of 99, and it’s genuinely one of the higher RTP ratings you’ll come across in the online pokies world — Relax Gaming built this one squarely for players who care about the maths behind a game as much as the theme.
Speaking of theme, it’s ancient Greek mythology wrapped around high volatility and fixed paylines, so wins land less often than on a low-variance game but tend to hit harder when they do — helped along by a multiplier that can stretch to 12,075x. Two mechanics do most of the heavy lifting on top of the base reels: a collection bar that pays out gradually as it fills, and a free spins round with expanding symbols for the bigger swings.
A free version sits directly on Relax Gaming’s own site, which is worth using first if you want to see the dynamic paytable in action — the win values update in real time as you change your stake, so you can get a feel for the numbers before risking anything.
Book of 99 pays back 99% of wagered funds over time, one of the higher return-to-player rates you’ll find on an online pokie.
Yes — triggering the bonus round drops you into a free spins feature where expanding symbols can land on the reels.
The multiplier can climb as high as 12,075x, giving the high-volatility reels a genuinely big top end.
