How to Play?

Find unique triangle from the grid.

The goal is to find the one unique triangle in a 3×3 grid within 100 seconds. Eight of these triangles are identical, but one is different and marked uniquely. To increase game difficulty, each triangle is rotated randomly, with a black line beneath it indicating its orientation.

1. Click on the one you think is different. It will light up red.

2. If you’re right, you get 5 points and automatically move to the next round. If you’re wrong, keep guessing by clicking on another triangle.

3. You can keep playing to get as many points as you can until the time runs out.

Tips to Win:

• In your quick review of the grid, focus more on any triangle that noticeably differs from the rest in triangle area.
• Find the right mix of quickness and precision to boost your score the most.
