Happy Cups and Balls

Happy Cups and Balls is a really fun game with a puzzle. The game rules are very plain. Turning on the tap and pouring balls into the cup is your duty. There's only one chance you have, so you have to regulate the volume of balls. It should be noted that the first half of the level is relatively easy, but it is very complicated in the second half of the level. Stop barriers, use your ingenuity and imagination, and fill all the cups!
