A little moment of focus

Reaction & memory

Wait for a signal. Remember a pattern.
Choose what you feel like trying today.

Respond to a signal

Reaction Time

Wait for TAP, then press with your selected input. An early press means retrying that trial.

A run: 5 valid trials · take a break between trials
Your result: Median time in milliseconds · lower is faster
Saved here: Best completed median for each input type

Open Reaction Time

Choose mouse, touch, pen or Space in the game. Leaving interrupts the current trial; a reload starts a fresh run.

Remember positions

Pattern Memory

Look at lit tiles for 4 seconds. After they hide, select the same positions—not a sequence.

A run: 5 rounds · no time limit for answering
Your result: Correct target tiles out of 22 · higher is more
Choose in the game: Daily (UTC) or practice · resume a saved attempt

Open Pattern Memory

Daily first results and practice bests are separate. Leaving during a reveal marks the attempt interrupted; the reveal is not shown again.

Your own play, not a ranking

These are playful challenges, not assessments of health, intelligence or ability. There is no combined score, percentile or age comparison.

Reaction times depend on the device, browser and input. Compare only your own runs with the same setup. Pattern Memory daily, practice and shared replays are different records; replays do not replace the first daily result.

Records stay in this browser on this site when storage is available. They do not sync across devices. Clearing site data can remove them. This page does not read, combine or change your saves; open a challenge to see its records.
