Our take
A 3x4-to-expanding Book of Infinity Reels hybrid with 96.50% RTP, 5,000x max win, and golden book scatter mechanics.
Red7's fusion of two popular mechanics—Book of and Infinity Reels—creates a high-ceiling win structure. The game begins with a 3x4 grid, which is tighter and more volatile than the standard 5x3 baseline. As players advance, adding reels expands the grid and increases a progressive win multiplier; this progression is the core tension of base gameplay. The golden book scatter appears on a randomly selected reel number, and you advance by landing matching new reels to that count—a clever mechanical twist that ties progression directly to scatter placement.
The 96.50% RTP is excellent for high-volatility games, and the 5,000x max win is legitimately substantial. Betting flexibility (20p to £50 per spin) accommodates various bankroll sizes. The Infinity Reels component introduces mechanical complexity: base-game play becomes a race to expand the grid and unlock progressively higher multipliers before the round concludes. For players who enjoy ladder-climb mechanics and the Book concept, this represents genuine innovation rather than iteration.
