All games
Doodle Jump sets the tone: one screen, a few keys, a score you want to beat. Around it are the games that play the same way in a spare ten minutes — tower climbers and hop-and-land platformers, endless runners, quick sports and driving games, arena shooters for two on one keyboard, and puzzles that save in the browser. 100 of them, all free and all playable in the page, each with its own guide.
