Zeus 3

Zeus III is a fantasy-themed online slot from WMS Gaming that takes you to the home of the Greek gods on Mount Olympus where you come face-to-face with the ruler of the gods, Zeus. While you might not benefit from the divine powers that Greek mythology's biggest deity boasts, you do have six reels and one hundred and ninety-two paylines to create wins with. The unconventional reel set which gets larger towards the right-hand side gets flipped around in the Free Spins Bonus to give you the ability to land more frequent and more valuable winning combos. And, the King of the Gods himself acts as both a stacked and expanding wild.

More about the Software Provider

WMS Gaming was created in 1991 as a subsidiary of WMS Industries, and it quickly became one of the biggest players in the video lottery terminal market. Building on its success with VLTs, WMS went on to produce video poker games and slots for land-based casinos. One of its greatest achievements was a slot game called Reel ‘Em In – a fishing-themed slot that was released in 1997.

In the 2000's, WMS Gaming continued to manufacture both physical and online slots, and in its current role as a subsidiary of Scientific Games, the company presses on with what it does best – producing highly-playable slots such as Crystal Forest HD, Zeus God of Thunder, Aftershock, KISS, and Montezuma – many of which can be enjoyed on mobile devices.

Appearance and Sound Effects

According to Greek mythology, the home of the gods was a temple on a mountain called Mount Olympus, but in the Zeus III slot game, the majestic temple appears high above the clouds surrounded by rays of sunshine. The atmospheric sounds of wind, birdsong, and choir voices play in the background, and whenever the Zeus symbol appears, the screen is lit up by the appearance of a massive lightning bolt at the same time that a rumble of thunder is heard.

The reel set that's used in Zeus III is different to what you might expect from a typical online slot. It's six reels wide, and it expands in height from left-to-right so that Reel 1 is two rows high and Reel 6 is seven rows high.

The paytable symbols are, in the main, inspired by Greek mythology, and they include Zeus, Pegasus, a silver coin, a warrior's helmet, a Grecian urn, a warship, a hand clutching a lightning bolt, Mount Olympus, and the four playing card suits.

Bonuses and Special Features

The image of Mount Olympus (the temple) is the wild symbol in Zeus III, and it can help you win cash prizes by replacing all symbols except the scatter symbol.

The Zeus symbol often lands stacked on the reels, and whenever a full stack appears, it transforms into a Wild Reel, i.e., when it's not stacked, it only acts as an ordinary symbol.

The scatter is the picture of Zeus' hand wrapped around a bolt of lightning, and it only appears on Reels 2, 3, 4, 5, and 6 in the base game. You need three scatters anywhere in view to access the Free Spins Feature. Three scatters give you ten free spins; four scatters give you twenty-five free spins and ten times your total bet, and five scatters give you fifty free spins and fifty times your total bet.

During the Zeus III Free Spins Bonus, the scatter symbol can appear on Reels 1, 2, 3, 4, and 5, and three or more add five extra free games to the outstanding total. To make things even more interesting, the reel set is flipped around in the Bonus so that the taller reels are on the left-hand side and the shorter reels are on the right-hand side, making it easier to create wins.


Zeus III uses six reels, between two and seven rows of symbols, and 192 paylines, and it comes with an excellent RTP (Return to Player Rate) of 96.1%. Winning combinations must occur on adjacent reels, beginning with the leftmost reel.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls.
