What is Simon Game?

Simon Game tests your memory with a sequence of colors and sounds that gets longer each round. Watch the pattern light up, then repeat it by tapping the colored pads. How far can you go before making a mistake?

Each round adds one step to the pattern, so a perfect run at round 20 means recalling 20 colors in order. Every pad has its own musical note and a unique shape, so you can play by sound or by color — and you can stretch to six pads for a tougher pattern. Your best round is saved locally between sessions.

How to use

1. Press 'Start' to begin. Watch as one of the colored pads lights up with a tone.
2. Tap the pads in the exact same order shown. Each successful round adds one more step to the sequence.
3. Keep going as long as you can — your high score is saved so you can try to beat it next time.

When to use

• Killing five minutes while you wait for a build or a kettle to boil.
• Training short-term memory the same way the 1978 toy did, no batteries needed.
• Settling a who-can-go-furthest argument with a sibling or coworker.

Result

Round 1 flashes green. You tap green. Round 2 flashes green then red. You tap green, then red. By round 8 the sequence is green-red-blue-yellow-red-green-blue-yellow and you really have to concentrate to keep up.

FAQ

How does scoring work — what counts as a high score?

Your score is the highest round you finished without a mistake. Reach round 12 and miss the 13th color, your saved best is 12. It is stored privately on your device — tap the trash icon next to the score to wipe it and start fresh.

I'm colorblind — can I still play?

Yes. Each pad carries a unique shape — circle, triangle, square and star, plus a hexagon and heart once you switch to six pads — shown by default. If they distract you once the colors are memorized, the toggle in the corner hides them.

Does the speed get faster as the sequence grows?

With the fixed Slow, Normal and Fast settings the flash length stays the same all game. Pick Auto instead and it starts gentle, then shaves a little off the timing each round so the pressure builds on its own — handy when you don't want to commit to one pace.

Why do the pads make musical notes?

The original 1978 Simon assigned each color a pitch from an E major arpeggio so the pattern doubled as a tune. We kept that — green is G, red is A, yellow is C, blue is E. The sound menu swaps the timbre between electronic, piano and xylophone without changing those notes, so the melody stays the same.

Can I play with the keyboard instead of tapping?

Yes. On a desktop the keys Q, W, A and S line up with the four pads (top-left, top-right, bottom-left, bottom-right), and the arrow keys work too. You can still Tab to a pad and hit Enter or Space, or just tap with a mouse or finger.
