Another Egyptian tomb, another sacred book. Book of Tutankhamun from Genii doesn't pretend to reinvent the formula, and that's part of why it works. The reels sit framed by sandstone carvings, pyramids drift in the background, and a blonde explorer in an Indiana Jones hat squares off against Tutankhamun's golden mask in the symbol pool. You've seen this setup a hundred times. The question is whether the math underneath earns its keep.
The grid is a tidy 5×3 with 10 paylines running left-to-right. Bets stretch from $0.01 up to $25.00 per spin, with five chip sizes and a fixed 5 coins per line. Genii doesn't publish an RTP figure for this title (a small annoyance if you're the type who likes to know the house edge before sitting down), but the feature set points to medium-high volatility. The official paytable caps top win at 5,800 coins, which is genuinely modest by 2026 standards. Modern Book-of clones often promise 5,000x your bet. Here you're looking at closer to 2,300x at maximum, and that's only if a high-pay symbol expands across all five reels in free spins.
The Book itself does double duty. It's a Wild that substitutes for any line symbol, and it's a Scatter that triggers the free spins round when three or more land anywhere on the reels. Land that trio and you're awarded 10 free spins, regardless of whether you hit three, four, or five Books. A short animation picks one symbol at random from the pool. That chosen symbol becomes the Special Expanding Symbol for the entire bonus round, expanding to fill the whole reel whenever it appears and paying as a scatter on the active lines.
One small touch worth flagging is the generosity on the top four symbols, which pay for just two of a kind on a line. That keeps the base game ticking over more often than the typical low-payline Book clone would suggest. There's also a classic Gamble feature: after any win, double up by guessing card colour, or quadruple by guessing the suit. Risky, old-school, and entirely optional. Free spins can't retrigger, which is the one rule that keeps sessions grounded. Pure Book-of formula, executed cleanly, with nothing trying too hard.
