Ball Sort Puzzle is a sorting game that requires a player to use their deductive reasoning skills to determine the correct steps to take to sort balls by color into laboratory test tubes across hundreds of levels. The test tubes hang in the foreground of an outdoor nighttime scene.
The player can only move a ball or balls to a tube that has enough empty spaces and a color-matched ball. Whenever they sort one color of balls, a test tube shoots colored confetti. If they run out of empty space, they can become stuck. When they only need to sort balls of one remaining color, the game automatically sorts the balls.
Ball Sort Puzzle features several tools designed to help the player sort faster and more efficiently. It offers an undo button marked with a back arrow and a hint button marked with a light bulb. It also offers the player the option to add an extra test tube to the playfield, but the player must watch an advertisement to use the tool.
The game doesn't feature a timer, but it does make the sorting process difficult in other ways. As the player progresses through each level, the game starts to mix balls of slightly different shades of each color. The player also can't use the extra test tube option if they use an ad blocker.
