Zeus III Slot Review

Zeus III is the first WMS Gaming-powered video slot to use the Reel Boost game engine. It has an innovative 6 reel layout with 192 paylines in total. The game is the third Zeus slot to be produced and is based on the Greek God of Sky and Thunder. It’s a high variance game with a unique flipped-reel mechanic in the free spins feature too. You can play Zeus III from as little as 40p a spin to as much as £120 a spin.

Zeus III follows on the back of the iconic Zeus slot (Zeus II is a Facebook slot for some reason). You can have wins of Olympian proportions with unique and innovative features. Firstly, you have a Free Spins feature which is triggered by getting 3 or more Coliseum feature symbols on consecutive reels (2 through to 6). You will receive 10 free spins for 3 feature symbols, 25 free spins and 10 times your stake for 4 feature symbols and 50 free spins and 50 times your stake for 5 feature symbols.

You will notice the reel layout is different and flipped from the base game (opposite basically) – this gives you the chance to line up multiple wins per free spins. Furthermore, any Zeus symbol appearing on a reel nudges to fill the entire reel with wild symbols – this is known as the Nudging Wilds feature. If you get a full reel of logo symbols, it will transform into a Nudged Reel which is a wild reel effectively. This is where the big wins can come from as getting 3 or more wild reels will really give you God-like wins.

In terms of the wins, the majority of the bigger wins should come in the Free Spins feature but over 57% of wins should come in the base game – they key is getting wild reels basically. In the Free Spins feature, getting the Zeus symbol on 3 or more reels will give you 3 or more wild reels which should give you huge wins. I found Zeus III to be quite volatile with small wins quite often – however, when the bigger wins come, I haven’t been disappointed (just need to be patient). This game is hugely popular in land-based casinos in the States – and now it’s online to enjoy.
