it was a little misleading on the box...i thought it was just a bunch of minigames to play. what happens is you go around to wario's different friends and they challenge you to X number of minigames, but you only have about 5 seconds to complete each one. as you complete more games, the time speeds up. what makes this fun is there are no directions, they tell you one word as a clue like "dodge" or "eat" in order to complete the 5 second game.
only 2 buttons are used (A and control pad), some games are really easy, some take a few tries to figure out, but they're all funny as hell (ex: pick your nose, eat a banana, swat a fly, etc) eventually as you complete the games one by one, you can go back later to play them individually. there are a few 2 player games to unlock, along with full games like "skateboard" or "jumprope". definitely worth the buy! (especially with over 200 games)
