Book of Eye is a video slot from Only Play, released in 2021, that follows the trail of ancient books and explorers. It has 10 paylines and a bonus buy option.
The theme is ancient books and explorers, an adventurous and inquisitive atmosphere. That sets the scene, but money results are decided by the numbers and by chance. With 10 paylines the line count stays moderate, so there is no complicated structure to keep track of.
Volatility is high. That usually means wins are rarer but cover a wide range of sizes, so sessions can swing in very different directions. The maximum win is 28,100 times the stake, a ceiling that fits that kind of variance, though it is not something to expect.
The RTP is 95.55%. That payout share only materialises in theory across a very long string of spins, so over a short stretch the gap can be large. In a high-volatility game it pays to size your stake so the budget lasts through quieter stretches.
The game includes a bonus buy option that lets you pay for direct access to an extra feature. It suits players who know high-volatility games and are ready to spend a pre-agreed amount on it, but it should never be used to win back earlier losses.
