By Matthew Kennedy | Updated 4 March 2024

SG Digital take you on a journey to Ancient Egypt with their new slot release, Book of Ultimate Infinity, where you have the potential to win up to x5,000 your wager.Features include Infinity reels, expanding symbols, free spins and multipliers. This is a high variance slot with an RTP set at 96.50%.

Slot details

Book of Ultimate Infinity begins with 3 reels and 4 rows with no limit to the amount of reels that can be expanded. It is available to play across all devices with wagering starting from 20p up to £50 per spin.The ornate gold framed reels sit on a desert backdrop with pyramids and palm trees. Symbols consist of the Jack to the Ace royals, an Egyptian Queen, a bird statue, an ankh and a Pharaoh. The latter is worth x25 your wager for 5 on a payline.

Gameplay

Landing 3 matching symbols on the 1^st, 2^nd, and 3^rd reels adds an extra reel to the game and a progressive multiplier comes into play, starting from x2. Each further reel added increases the multiplier by x1.To access the free spins you have to land the Gold Book scatter symbol which is hidden at random on reels 6-15. This starts you off with 10 free spins and a random symbol is selected to become an expanding symbol. If you land the special symbol or the book symbol on the last reel, another reel is then added. If the special symbol appears on at least 2 reels, it expands and fills that reel.Book of Ultimate Infinity is a really immersive game with clear visuals accompanied by an orchestral soundtrack. I enjoyed the infinite reels and the fact that the scatter symbol is hidden; it added more excitement to the game. The maximum payout is capped at £250k which is still a nice tidy sum to win.
