Train your brain, match, tap, flip in the Color Tube Sort game. Your task is to sort the colorful balls. Each test tube should contain three identical balls. When sorting, you can place a ball on the same color or in an empty test tube. You can also add a fourth ball during the sorting process, but the containers should end up with three balls in the Color Tube Sort. Complete the levels, and at each subsequent level the tasks become a little more difficult.
