A grid of near-identical emoji hides one that is slightly different. Tap it as quickly as you can. Your time is shown when you find it.
Don't try to read every emoji. Let your eyes relax and scan for what stands out, in sweeping lines across the grid.
Different pairs of emoji are harder than others, so your time will vary from round to round.
Frequently asked questions
What is this game testing?
Visual search: how quickly you can spot a small difference in a crowd.
Why do some rounds take longer?
Some emoji pairs look much more alike than others.
Is a wrong tap penalised?
No. The wrong cell flashes and you can keep looking.
