WarioWare, Inc.: Mega Microgames!

ADHD kids rejoice. Your messiah is here in video game form!

Simple but wackily presented rapid-fire minigame collections like this had been popular in Japanese arcades for a long time, but Nintendo really did a fine job adding the variety and polish needed to make this a genre that would work as a handheld game people would actually want to come back to, with plenty of variety, charming presentation, and variable difficulty (though I wonder how many people stuck around for the hardest versions of everything). Also, the Fly Swatter game from Mario Paint.

Wrestled with Tetris for the best gameboy game to play while pooping before iPads and smartphones

if monty python made a series of games it would be warioware

Great game. You are doing challenges here as fast as you can. So just memorize and be quick with your hand eye coordination.
