FEATURES: • No Ads. • One finger control. • FREE & EASY TO PLAY. • NO penalty & time limit. HOW TO PLAY: • Tap on any tube to move the ball at the top from one tube to another. • The rule is that you can only move a ball on top of another ball if both of them have the same color, or the destination tube is empty and the tube you want to move into has enough space. • You can undo your moves if you're stuck 5 times per level. • You can restart the level altogether.
