3 in-game Player-Versus-Player version of this minigame, each of the three uses causes the opponent to lose a card and all the enemies to be flipped over. It can be used three times before it disappears. The 'POW' block flips all enemies touching a platform or the floor when a player hits it from below. When bumped from below, the Slipice dies immediately instead of flipping over. There are four enemies: the Shellcreeper, which simply walks around the Sidestepper, which requires two hits to flip over the Fighter Fly, which moves by jumping and can only be flipped when it is touching a platform and the Slipice, which turns platforms into slippery ice.

Each phase has a certain number of enemies, with the final enemy immediately changing color and increasing its speed. If the player allows too much time to pass after doing this, the enemy will flip itself back over, changing in color and increasing speed. This is accomplished by hitting the platform the enemy is on directly beneath them. Enemies are defeated by kicking them over once they have been flipped on their back. The player gains points by defeating multiple enemies consecutively and can participate in a bonus round to gain more points. Both sides of every phase feature a mechanism that allows the player to go off-screen to the left and appear on the right and vice versa. Each phase is a series of platforms with pipes at each corner of the screen, along with an object called a 'POW' block in the center. Unlike future Mario games, players cannot jump on enemies and squash them, unless they were already turned on their back. The objective of the game is to defeat all of the enemies in each phase. features two plumbers, Mario and Luigi, having to investigate the sewers of New York after strange creatures have been appearing down there. The original versions of Mario Bros.-the arcade version and the Family Computer/Nintendo Entertainment System (FC/NES) version-were received positively by critics.

In the game, Mario is portrayed as an Italian-American plumber who, along with his younger brother Luigi, has to defeat creatures that have been coming from the sewers below New York City.
