EveryMemorySimon Task
The Simon Task is a free flexibility game. Color picks the button, not position, so your brain fights the urge to follow where the square appears.
⚡ Quick answer
The Simon Task is a fun self-check of response mapping and cognitive flexibility. BLUE means press LEFT and ORANGE means press RIGHT, no matter which side the square appears on. It reports your accuracy and median response time over sixteen trials, compares only to your own past, and is not a medical test.
Key takeaways
- Free flexibility game in your browser, no sign-up needed
- Color picks the button, position is the distraction
- Tracks accuracy and median time over sixteen trials
- Self-relative and saved on your device, not a medical test
The Simon Task is a quick decision game you can play right above. A colored square pops up on the left or right, but the color tells you which button to press, so where it lands is a distraction.
It is free, needs no sign-up, and your best accuracy is saved only on your device so you can beat your own past runs.
How to play
Learn the simple rule at the top, then watch the panel and play it above.
- Remember the mapping: BLUE goes to the LEFT button, ORANGE to the RIGHT
- A square appears on the left or right side of the panel
- Press the button that matches its COLOR, ignoring its position
- Repeat across sixteen trials and watch your accuracy and median time
No account is needed and your best accuracy is saved on your own device.
What it trains
The Simon Task asks you to follow a rule while resisting a strong, automatic pull toward position.
- Stimulus to response mapping
- Inhibiting an automatic side response
- Holding a rule in working memory
Be honest: you mostly get sharper at this game itself, and it is not an IQ measure.
Why incongruent trials feel slower
When the square sits on the same side as its correct button, the trial is congruent and feels easy. When color and position disagree, you have to override the position pull, and that small delay is the classic Simon effect.
- Lock onto the color first, then choose the button
- Expect the mismatched trials to cost you a beat
- Steady accuracy beats rushing into the wrong side
The honest way to read your score
Your accuracy and median time are personal markers, not a ranking against anyone else. Tiredness and your setup move them, so the only fair comparison is you versus your own earlier runs.

⚠ When to talk to a professional
This is a casual game for fun and self-tracking, not a medical or cognitive assessment, so see a qualified professional for any real concerns.
