A 45-second visual search game. Spot the one shape with a different direction, dot position or missing line, then move straight to the next round. The board grows from 3×3 to 5×5 as you progress. Play in your browser on desktop or mobile.
Choose Let’s play and click or tap the one shape that differs from all the others. Each correct choice earns 10 points and starts a new pattern. Wrong choices give a gentle cue without ending the game. After four cleared rounds the board grows to 4×4; after nine it grows to 5×5. After 45 seconds, see your score, rounds cleared and accuracy, then choose Play Again.
