The game requires sorting balls into tubes by color. i noticed the destination tube must be empty or contain matching colors to move balls.
Tap a tube to select it, then tap a destination tube to move the ball.
The game has 100 levels and 6 skins to unlock. There are no stated timers, hints, or extra toggles.
Group similar colors together before moving them. Planning ahead is better than just reacting.
