How to play
- Press Start. One pad lights up with a tone.
- Press the same pad. Then the game plays the sequence again with one more colour added.
- Repeat the whole sequence each round. One wrong pad ends the game, and your score is the longest sequence you repeated.
After round 4, then round 8 and round 12, the colours play faster. On a computer, keys 1 to 4 press the pads (green, red, yellow, blue), and so do the arrow keys: up, right, left and down.
Tips for longer sequences
- Say the colours. Naming them quietly, “green, red, red, blue”, gives you a second way to remember them.
- Listen to the tones. Each colour has its own note, so the sequence becomes a little tune. Many players find the tune easier to remember than the colours.
- Group them. Remember the sequence in chunks of three or four, the way you remember a phone number.
- Only add the new one. You already know everything but the last colour; each round, focus on the one that was added.
About the game
Simon was an electronic memory game released by Milton Bradley in 1978, with four coloured buttons that play a growing sequence of lights and tones. This page is our own free version of that kind of game, made for the browser. It is not affiliated with the makers of the original toy.
It is a sequence memory game: it tests how many items you can hold in mind in order. For a test of numbers instead of colours, try the number memory test, and for pictures, the memory game.
Frequently asked questions
How do you play the Simon game?
Watch the pads light up, then press them in the same order. Each round adds one more colour, and one wrong press ends the game.
What is a good score?
It depends on the player, and practice helps a lot. Beat your own best, which this page keeps on your device.
Can I play with the keyboard?
Yes. Keys 1 to 4 or the arrow keys press the pads, and Enter or the space bar starts a new game.
Can I play without sound?
Yes. Press Sound on to turn it off. The pads still light up, but the tones help many people remember.
Is this the original Simon?
No. It is a free version of the same kind of game for the browser, not connected with the original toy.
