Simon

Simon lights up a panel and plays its tone. Then it plays a two-panel sequence, then three, and so on — each round it adds one more panel to the end and replays the whole thing, a little faster each time. When it is your turn, repeat the sequence back by clicking the panels in the same order. One wrong panel ends the game. Your score is the longest sequence you repeat back perfectly. There is no time limit on a press — take as long as you need to recall it. You can also use the number keys 1–4 (green, red, blue, yellow).
