What this game is
Simon Says is the electronic memory game from 1978, rebuilt in your browser. Four colored pads flash a short sequence — one pad at a time — and you have to tap the same sequence back in order. Every round you survive, the game adds one more flash to the sequence. There is no limit: the sequence grows until you slip.
Unlike the number memory test, the challenge here is spatial and temporal: you are remembering where the pads are and in what order they fired, not what digits looked like.
How to play
- Press Start — the pads flash a sequence of 1.
- Repeat it: tap the same pads in the same order (or use keys 1–4).
- Level up: after each correct sequence, the game replays the full sequence with one extra flash added.
- One wrong tap ends the run — your best round count is saved on your device.
How the rounds speed up
Because the whole sequence replays every round, the game itself is your memory trainer: you re-hear the old flashes and only need to remember one new position each time.
Tips for longer runs
- Say the pads out loud: "blue, orange, green…" converts position into sound, which is easier to hold.
- Look for chunks: repeated pairs or runs are easier to remember than random positions.
- Rest your eyes: staring hard at four pads for ten rounds is genuinely tiring — a short glance reset between rounds helps.
Frequently asked questions
Can I play with the keyboard?
Yes — keys 1, 2, 3 and 4 map to the four pads, so you can play without a mouse.
Is the sequence random?
Yes. Each round's new flash is a fresh random pad, generated in your browser.
Where is my best round kept?
Locally in your browser's storage, on your own device. If you like this one, try Number Memory for digit recall, Memory Match for a math twist, or see all games.
