Simple but addictive puzzle game!
Click on any cup to move the ball at the top of the cup to another cup.
The rule is that if both balls have the same color and the cup to be moved has enough space, the ball can be moved.
You can restart the level at any time, or use the back button.
When you are stuck, you can add a cupqiu to reduce the difficulty of the game.
The game process exercises the logical reasoning ability very much, absolutely not to be missed!
