Book of the Cleo Slot by Zillion Games

Two separate bonus systems share one moonlit Egyptian riverbank, and that split is the main thing setting this apart from the dozens of Book of Ra clones it otherwise resembles. One path is the expanding-book free spins you already know. The other is a coin-collection round with its own jackpot ladder bolted on top.

Free spins arrive two ways: three golden book wilds, or three scatters. Either trigger drops you into the same round, where one symbol gets picked to expand across the reels in classic Book fashion, and a Multichance mechanic keeps accumulated symbols in play as the spins run down. The golden book doubles as the wild in the base game, substituting for regular symbols and paying its own way when three land.

The jackpot side runs through a Hold and Ring round. Land six coin bonus symbols and the respins begin. Coins lock, the empty grid positions spin again, and each new coin you catch holds its cash value until the round ends and pays out the total. Fill all 15 positions and the Grand lands at 1000x your stake. The Major, Minor and Mini plaques sit above the reels at 100x, 50x and 20x, awarded through the same round without needing a full board.

Any five-of-a-kind across a payline sets off a full-line celebration pop-up. Visually it commits hard to the Cleopatra fantasy: the queen seated on a golden lion throne to the left of a red-and-gold reel border, pharaoh masks as pillars, a dark blue Nile scene behind. Card ranks handle the low pays, with a blue Ankh, green scarab ring, red Eye of Horus and the Cleopatra portrait up top. Competent, good-looking, and about as by-the-numbers as Egyptian slots get.
