Odd One Out: a visual search test
Find the one shape that is different in a grid of look-alikes, as fast as you can.
Try a practice roundPlay today’s fiveHow it works
A grid of matching shapes hides one that’s different. Tap the different one as fast as you can. Three rounds, and tapping a wrong shape costs 300 ms.
What it measures
Visual search research shows that some differences pop out instantly while others need a careful scan. The harder rounds make the difference subtle enough that you have to look.
It measures how efficiently you search a scene, a skill used in everything from driving to finding a friend in a crowd.
What’s a good score?
In Reactdle, 1.1 s or faster rates Sharp, up to 1.6 s is Steady, and slower is Sluggish.
Tips
- Relax your eyes and look at the grid as a whole; the odd one often jumps out.
- Only scan row by row if nothing stands out.
