Super Mario Bros. Crossover is a Flash browser-based platforming game. The game's levels and graphics are all primarily duplicates of those found in Super Mario Bros.; each of the game's eight worlds feature four levels. In three of the levels, the goal is to reach a checkpoint to complete the level, while the final level has the player facing against Bowser in hopes of rescuing Princess Peach. Enemies such as Goombas, Koopa Troopas and Hammer Bros. will block the player's attempt to make it successfully through the level. As Mario and Luigi, the player can jump on enemies to kill them, use Koopa shells to knock enemies over, and acquire powerups from special blocks that serve to boost health, shoot fireballs, or remain invincible for a short period of time. Besides completing the level, the player can also earn coins and points, attempting to achieve a high score.

Crossover varies this formula by adding in several additional main characters in addition to Mario that the player can play. In the same manner as with Super Mario Bros. 2, the player selects one of the additional characters at the start of each level.  Each character, based on other classic Nintendo Entertainment System games, uses different attacks and movements that are related to their original game, as well as their own signature music.  These characters are:
Link, based on The Legend of Zelda, uses a sword and boomerang to attack enemies.  Collecting powerups increases the potency of the sword's attacks and the range of his boomerang. He is the only character with fundamental control changes from his original game, being given the ability to jump, which wasn't possible until Zelda 2.
Mega Man possesses the Mega Buster which he can use to fire forward to destroy enemies, with additional powerups to increase his firepower, and has the ability to slide under small spaces. Within version 1.1, Mega Man's jump height is reduced but now has the ability to call in Rush, his robotic dog, to assist in high jumps.
