What is the Simon Memory Game?

Simon is the glowing disc that tested a generation's memory: it plays a sequence of colors and tones, you play it back, and each round it adds one more — until your memory finally slips.

Play the classic here, free, with the lights and sounds that make it click.

What does this tool do?

The game flashes a sequence of colored pads, each with its own tone; you repeat the sequence by tapping the pads in order.

Get it right and the sequence grows by one; get it wrong and the game ends, showing how long a sequence you managed.
