Play Mappy (Japan) Online

Mappy is a 1984 NES game from Namco, originally an arcade port that found a solid home on the console. It arrived during a time when simple, fast arcade experiences were common on the system, offering a clear and focused alternative to more sprawling adventures.

You control Mappy, a police mouse, moving floor to floor across single-screen stages to recover stolen goods. Your main tools are the trampolines for vertical movement and the doors you can slam to temporarily stun the pursuing cats. The objective is straightforward: grab all the items on a stage while avoiding the persistent feline enemies, who become faster and more numerous as you progress. The game demands quick reflexes and smart use of the environment, like timing door slams just as a cat is passing through. It feels frantic but controlled, a constant push between grabbing loot and creating safe openings.
