Click on the same donuts nearby to eliminate them, and as long as you reach the game goal, you can enter the next level.

It can only be adjacent to each other in the top, bottom, left, and right directions. The more connected donuts there are, the higher the score, with a minimum of two adjacent ones.

Scoring technique:

1. Try to click on the ones with the most connections, but avoid disconnecting other long connections;

2. If possible, construct long connections for the later part;

This game has no time limit, think first and then operate.

In the above picture:

Click on 0 first, and the green in the upper right corner will drop 3 squares;

Then click on 1, and all 5 green donuts No.2 will be connected in a row;

Then click 2, and finally click 3, because if you click 3 first, 2 won't be in the same row anymore.
