How to play

You're shown a grid of identical colored tiles — except one, which is a slightly different shade. Click the odd tile out.

There are five rounds. The grid grows each round (3×3 up to 7×7) and the shade difference shrinks, so it gets genuinely hard by the end.

Alongside practice mode there's a daily challenge: the same seeded puzzle for every player that day, with exactly one attempt.

Scoring

• Your score is the total time to finish all five rounds — lower is better.
• A wrong click adds a 2-second penalty, which is roughly the cost of an entire extra round.
• Practice and daily runs go to separate leaderboards.

Tips

• Accuracy beats speed: one miss costs more than careful looking ever will.
• Scan systematically (rows or quadrants) instead of darting around the grid.
• Squinting or leaning back slightly can make the odd shade pop out.

Frequently asked questions

Why did my time jump by 2 seconds?

You clicked a wrong tile. Every miss adds a 2-second penalty to your total.

Can I retry the daily puzzle?

No — the daily challenge is one attempt per day, same puzzle for everyone. Practice mode is unlimited.
