The Wild symbol substitutes for all other symbols. Wild symbol substitutions pay the highest possible winning combination on a bet line, as per the Paytable.

At the start of each spin in the main game, there is a chance to activate the Wild-O-Tron feature. This feature transforms all occurrences of 1 to 6 robot symbols into Wild symbols during the spin. While active, the lamps on the Wild-O-Tron machine beside the reels light up in the colours of the transformed symbols. Wilds are the highest-paying symbols in the game. The feature is played using the same bet lines, bet level, and coin value as the activating spin. All Wild-O-Tron feature wins are added to the player’s balance.
