Another Egyptian book slot? Yeah, but Book of the Cleo from Zillion Games actually earns its spot. Cleopatra lounges on a golden lion throne beside a red-and-gold 5×3 frame, the Nile glinting behind her in the moonlight. It's a familiar setup, sure. Then you notice the four jackpot plaques bolted across the top, and things get more interesting.
The base game is deliberately old-school. Five reels, three rows, 25 fixed paylines, left-to-right pays only. High symbols run from the Cleopatra portrait down through a red Eye of Horus, a green scarab ring and a blue Ankh, with 10 through Ace filling the low end. The golden book is your wild, subbing for regular symbols, and land three of them and you're into the bonus round. Land a full five-of-a-kind line, and a little celebration pop-up fires off too.
Free Spins can trigger two ways: three golden book wilds, or three scatters. Once inside, a blue book becomes an expanding symbol in true Book-of-Ra fashion, picking one icon to stretch across the reels. A Multichance mechanic runs alongside it, and accumulated symbols stay in play across the round. That's where the 1675x max win realistically comes from.
The Hold & Ring feature is the other draw. Six bonus coins kick off a hold-and-win respin: coins lock, empty spots keep spinning, and when it settles you collect the summed values. The 5×3 board has 15 positions, and here's the hook: fill every single one and the Grand jackpot pays 1,000x your bet. Below that sit Major at 100x, Minor at 50x and Mini at 20x.
Now the honest part. RTP is 95.35%, which is a touch below what I'd want on a high-volatility game like this, and the 1.98% hit rate means dry patches are the norm, not the exception. There's no bonus buy either, so those jackpots come only when the game decides. Is that a dealbreaker? Not really. But you'll want patience and a bankroll that can wait. For fans of classic Egyptian expanding-symbol slots with a jackpot twist, Cleo delivers plenty to chase.
