Need a good reason to spin this slot machine into action? Well, how about three? While playing the Wild-O-Tron 3000 online slot, our review team found substituting wilds, stacked robot symbols, and an electrifying random feature that creates wins worth up to 500x your stake on every spin. Seven uniquely designed robots buzz and beep their way onto the reels. When the perfect robot is built and matched across at least three reels – beginning on the leftmost reel – a powerful bolt of electricity will shoot across the paylines to highlight that you’ve created a winning combination.
