The game requires minimal manipulation of the reel set to be played. Players must locate the coin stack button in the bottom-left corner of the screen, activate it, and select one of the available wager amounts per monster drop.
In this regard, the Mad Monsters slot machine accepts wagers between 0.25 and 250 per turn. Regardless of the amount wagered, the game always generates drops with the maximum potential to produce the largest successful outcomes and win multipliers.
The options accessible via the menu icon include sound effects, music, and turbo spins. The 'i' button exposes the paytable, where players can view the symbol payouts for each monster and fruit, as well as details on the additional features.
Five corresponding symbols that are adjacent to one another constitute a winning combination. When a successful outcome occurs, the symbols are removed from the grid and replaced with a new set.
The most valuable symbol in the Mad Monsters slot machine is the four-eyed purple-indigo creature, which can pay out 1,000 times your wager divided by the fixed wager of 25. This compensation applies to clusters of 20 to 49 symbols. Clusters of five to 19 symbols pay between 7x and 400x their base value.
The woolly monster, the strange yellow-bodied woman, the green substance, the purple chick, and the red crab-like monster pay between 2x and 5x for the lowest possible outcome of five symbols, and between 125 x and 400x for the best possible outcome of 20 to 49 symbols.
