Try the Spot the Change test free online. Memorize a colored grid, watch it flash, then tap the cell that changed. A fun change-blindness self-check.
⚡ Quick answer
Spot the Change shows a colored grid, briefly blanks it, then redisplays it with one cell changed for you to identify. It exercises short-term visual memory and change detection. Your score is the number of rounds you clear, saved on your device so you only compare with your own best. It is a fun self-check, not a medical test.
Key takeaways
- Memorize a colored grid, then spot the one cell that changed after a flash
- Each round adds cells; three wrong answers ends it
- Free in-browser, no sign-up; best round count saved on device
- A self-relative change-blindness check, not a diagnostic test
Our brains are surprisingly blind to changes that happen during a brief interruption - a phenomenon called change blindness. This game lets you experience and practice spotting those changes.
Play it above - tap Start, memorize the colored grid, and after a quick blank flash, tap the single cell that changed colour. Each round adds more cells to track.
How to play
Hold the whole grid in mind, not just one corner.
- Tap Start and memorize the colored grid
- Watch the brief blank flash
- When the grid returns, find the one cell that changed colour
- Tap it - three wrong answers ends the game
No account is needed and your best round count is stored locally on your device.
What it trains
This game targets a specific kind of visual memory.
- Short-term visual memory for colour and position
- Change detection across a brief gap
- Whole-display attention rather than tunnel focus
You mainly get better at this game with practice. Enjoy it as an intriguing brain teaser, not a measure of intelligence.
Why the flash matters
The blank flash is what makes spotting the change hard.
- It wipes the visual afterimage you'd otherwise compare against
- This forces you to rely on actual memory
- Bigger grids overload that memory faster
- Mentally grouping cells by colour helps a lot
The honest way to read your score
Rounds cleared will vary with focus and grid luck, so compare only against your own earlier sessions and watch the trend.
