About Simon Says

Play Simon Says free online — repeat color and sound patterns that get longer each round. Fun memory game that builds focus and recall for kids ages 4-12. No ads.

How to use

1. Pick a speed: Slow (each color shines for 800ms with 300ms gaps — best for ages 4-5), Normal (500ms / 200ms — the classic Simon pace), or Fast (300ms / 120ms — challenge mode for older kids).
2. Press Start. The four pads (green, red, yellow, blue) take turns lighting up with their own musical tone — each color has a different pitch, so the sequence is both visual and auditory.
3. Round 1 plays a 1-color sequence. Tap the same color back. Each successful round adds one more color to the front of the next pattern, so Round 5 means remembering and replaying 5 colors in order.
4. One wrong tap ends the game. Your high score is the longest sequence you reproduced perfectly, and it saves locally in your browser for next time.
5. Use the chunking strategy: group the colors into pairs or triples in your head ('green-red, then yellow-blue, then green') instead of one-at-a-time. This is how memory champions handle long digit strings.
6. Confetti celebrations fire automatically at rounds 5, 10, 15, and 20 — concrete reward markers that keep younger kids motivated.
7. Simon trains short-term memory and sequential processing — the same working-memory circuit measured by digit-span tests. Cogmed and similar working-memory training programs use almost identical sequence-recall mechanics. Free, no sign-up, no ads, large pads sized for tablets.
