Developed by Apollo Game Studio, Ball Sort Puzzle – Egg Sort is a mind-bending game that challenges players to skillfully arrange colored balls into matching tubes. This entertaining puzzle is a great way to hone your cognitive skills while also allowing yourself to mentally relax and indulge in an enjoyable experience.

In order to play, you must deftly tap on the tubes to move balls from one to the other. However, the game rules require that you only place balls of the same color on top of one another, and you can’t overfill any tube. Fortunately, you have the option to add a tube to make things a bit easier, or to undo previous moves in case you get stuck.
