Sort Colored Balls Puzzle is a three-dimensional sorting game. Against a gradient dark blue background, the player sorts a mix of colored balls in test tubes across levels. Their main goal is to rearrange the balls to fill each test tube with only one color. Their other objectives are to win coins and stars and unlock all levels.
The player places one or more color-matched balls atop identical ones or into empty test tubes. Unlike similar games, they can select a stack of color-matched ones of any size. The game auto-splits the stack.
For example, if the player wants to transfer two blue balls to an empty space above a blue stack that has enough room for both, the game auto-transfers the entire stack. If there's only enough room for one, it splits the group by transferring a single ball and leaving the other behind.
Sort Colored Balls Puzzle rewards the player with the most coins and stars as a time bonus. As a result, the player must finish rearranging the balls as quickly as possible within an unknown average number of seconds.
The game helps the player move faster with three tools. They can use a button labeled with a question mark (?) to see a hint. They can use a button labeled with a plus sign (+) and a test tube icon to add an empty extra container to the field. They can use a back arrow button to reverse one or more previous moves.
