In the main game, the player has to place blocks on a grid with the goal of making a path for a Mini (a small walking robot that looks like Mario or another character in the "Mario" series) to get from a warp pipe to the goal. The player has to avoid obstacles like Shy Guys and spikes. Each level has three colored coins that the player can collect. Collecting all three coins gives the player a star token. Star tokens can be used to unlock more gameplay modes, levels, and toys. There are more than 180 levels in four modes of gameplay. There are also four minigames that can be unlocked.
