How to play Odd One Out
Find the one tile that differs from every other tile. Ten untimed rounds begin with shapes, then move to arrow directions and ring gaps.
- Choose one tile per round. A correct first choice earns 1 point; an incorrect choice earns 0.
- After each choice, the answer is marked. Select Next round when you are ready.
- The grid grows from 3 by 3 to 4 by 4. Differences are in shape or direction, never only colour.
- Finish ten rounds for a score out of 10. Play a fresh set to try again.
Controls

Frequently asked questions
Is there a time limit?
No. Take as long as you like. Switching tabs or reloading does not cost points; a saved set resumes when browser storage is available.
Can I change my answer?
Each round records one choice, then shows the answer. You cannot retry that round for points, but you can play a fresh set after finishing.
