Book of Zeus

Book of Zeus by AmigoGaming is a video slot played on a 5-reel, 3-row grid with 10 fixed paylines. The theme is Ancient Greek mythology, featuring Zeus, Pegasus, temples, ships, and skies of Mount Olympus as symbols and backdrop. The Book symbol serves both as Wild and Scatter in the base game: as Wild it substitutes for regular symbols to help complete winning combinations, and as Scatter it triggers the Free Spins feature when three or more land anywhere on the reels.

When Free Spins are triggered, you receive 10 spins and one special symbol is randomly selected. That symbol becomes “expanding,” meaning that if enough of those appear during the free spins, they expand vertically to cover all positions on their reels. Expanded symbols can pay even if they’re not on adjacent reels (as long as they appear on fixed paylines). The free spins round can be retriggered by landing more Scatter/Wild Book symbols.

In the base game there is no separate bonus round beyond the free spins feature, but there is a Bonus Buy option that allows players to buy direct access to the Free Spins feature instead of waiting for the natural trigger. The maximum possible win reaches up to 6000× the bet. Book of Zeus is a high variance slot, meaning big wins can happen but they are less frequent, and it includes standard wilds/scatters, fixed paylines, and the expanding-symbol mechanic during free spins.

You can play it for real money.
