Simon

About Simon

Simon is a classic electronic memory game from 1978. The device shows a sequence of lights and sounds, and the player has to repeat that exact sequence back. Each successful round adds one more step, so the pattern grows longer and longer until your memory finally slips. This browser version keeps the four colored pads and the same escalating challenge — it's a deceptively addictive test of your short-term memory and focus.

How to play

• Press Start and watch the pads flash in order.
• Repeat the sequence by clicking the pads in the same order.
• Get it right and the sequence grows by one each round.
• One wrong pad ends the game — try to beat your best round.
