TouchMaster 3's Counterweight.

TouchMaster 3 (Warner Bros.; DS; rated everyone)

While many games claim to fill the need for a quick five-minute gaming hit when you need it, TouchMaster 3 actually does.

It’s a simple collection of 20 games that fall into five different categories: word games (Wild Words has you building a crossword by arranging letters on a grid), puzzle games (Tetris- and Bejeweled-like games), action games (in Electro Maze you guide a ball through a maze, avoiding touching the electrified walls), strategy games (Counterweight has you trying to balance two scales to match a number), and card games (most of which involve building poker hands).

All of the games are easy to play, although some will take some time to master. And because the DS will automatically pause your game when you close it up, you can stop and start at any time, even if you’re killing at the Chef Memory game.
