Zeus is an extremely popular slot, both online and on land. It's popular largely because of the free spin bonus as well as the frequent stacking wilds that appear fairly often. Imagine being one of the lucky ones who lands 100 free spins, plus stacking wilds and retriggers on the free spins. There are 5 reels with 30 paylines, so the chances of winning are great! With a big thrill factor and great media effects, WMS is on to a winner here.
