Book of 99 Slot: The Only 99% RTP Slot Machine You Need to Know
If you’re searching for a slot machine that offers an exceptional 99% return-to-player (RTP), the answer is Book of 99 by Relax Gaming. This slot stands out as one of the few video slots with an RTP as high as 99%, which means it theoretically returns $99 for every $100 wagered over the long run. Most online slots have RTPs between 94% and 96%, so Book of 99’s 99% RTP is significantly higher than the industry average and makes it a top choice for players who want to maximize their theoretical returns.
Book of 99 features 5 reels and 3 rows with 10 fixed paylines, and it offers a maximum win of 5,000 times your stake. The game has high volatility, which means you may experience longer periods without wins, but when you do win, the payouts can be much bigger. The developer Relax Gaming is known for creating innovative slots, and this one follows the popular “Book” mechanic where a special Book symbol acts as both a wild and a scatter symbol.
The Book mechanic in this slot works similarly to other well-known Book slots like Book of Ra, where landing 3 or more Book symbols triggers free spins with a special expanding symbol. During the free spins round, one regular symbol is chosen at random to become an expanding symbol that can cover entire reels, increasing your chances of landing winning combinations. This feature is what makes Book of 99 exciting and gives players the opportunity to hit big wins up to 5,000 times their bet.
While Book of 99 is the primary slot with exactly 99% RTP, there are other high-paying alternatives you might consider if this game is not available in your region. For example, 1429 Uncharted Seas by Thunderkick offers 98.6% RTP, Marching Legions by Relax Gaming has 98.12% RTP, and both Money Cart and Money Cart 2 by Relax Gaming offer 98% RTP. Mega Joker by NetEnt also offers 99% RTP but only when you bet the maximum amount, making Book of 99 more accessible since its 99% RTP applies to all bet sizes.
Remember that RTP is calculated over millions of spins and does not guarantee short-term results, so even with a 99% RTP, you can still lose money in a single session. High volatility slots like Book of 99 may have longer dry spells between wins, but they also offer bigger potential payouts when wins do occur. This makes Book of 99 an excellent choice for players who understand the balance between risk and reward and want to play a slot with one of the best theoretical returns in the industry.
