How to play Simon

  1. Press Start. Simon flashes one pad with a tone.
  2. Repeat the sequence by tapping the pads in the same order.
  3. Each round adds one step to the sequence.
  4. Wrong tap = game over (or a replay of the sequence in training mode; in strict mode a mistake restarts from round 1).
🧠 Memory trick: give each color a word or rhythm ("green-red, green-red-yellow") and say it in your head. Chunking the sequence into pairs is how memory athletes do it — most beginners jump from 6 to 10+ rounds with this one trick.

Why Simon is a great brain workout

Simon trains working memory — the mental scratchpad you use to hold a phone number, follow multi-step instructions, or keep a shopping list in your head. Because the sequence grows unpredictably, your brain can't coast: every round demands full attention. A few minutes a day is a genuinely fun way to sharpen focus, for kids and adults alike.

Frequently asked questions

How do you play the Simon memory game?

Simon flashes a sequence of colors with sounds; you repeat it by tapping the pads in order. Each round adds one step. A mistake ends the game — or replays the sequence in training mode.

What is a good Simon score?

Most casual players reach 8–12 rounds. With the chunking trick (grouping colors into pairs or rhythms), 15+ is very achievable. There is no maximum — the sequence grows until you fail.

Does playing Simon improve memory?

It exercises working memory and sustained attention. Regular short sessions genuinely sharpen focus, like any consistent mental exercise.

What is training mode?

A forgiving mode where a mistake replays the sequence and lets you retry the same round until you get it right — ideal for learning longer sequences.
