Our take
High-volatility Egyptian slot from Light & Wonder with expanding reels, stacked symbols, and multiple reel configurations.
Book of Ultimate Infinity takes the Egyptian theme and pairs it with a reel-expansion system: the base game starts on three reels but can expand during free spins or bonus rounds to unlock additional reel sets. This mirrors the mechanic seen in Pearl of the Caribbean but applies it to a high-volatility framework, dramatically escalating potential payouts. At 96.78% RTP and high volatility, the game skews toward players comfortable with long dry stretches followed by substantial clusters.
Stacked symbols (where a single position can hold multiple copies of the same symbol) increase the probability of filling entire reels with a matching type. When combined with expanding reels and free spins, stacked symbols can trigger reel expansion conditions more frequently, creating momentum within bonus rounds. Win multipliers—likely x2, x3, x5, or higher—amplify payouts as the feature progresses, rewarding prolonged free spins.
The three-to-multiple-reels progression creates psychological intensity: early free spins on three reels feel modest, but watching additional reel sets unlock and payline counts explode generates tangible excitement. The Egyptian artwork is polished and detailed, with animations responding to wins and feature advances. For players who find standard 5-reel games predictable, the reel-expansion novelty is genuine.
