Caisses

Sokoban is one of the most challenging puzzle games in which you have to push boxes in a warehouse to their storage locations. However, you can only push but not pull boxes, and only one box at a time. In order to complete a level, all the boxes must be placed in their storage locations. The game was first released more than 30 years ago, so if you are looking for new levels, then you should try this game. Cassies is nothing more than a collection of 500 Sokoban-like levels, which will keep you playing for hours.

This game features decent graphics and animations, and it is really easy to play. You have to control your character, the warehouse keeper by using the arrow keys, and you can use up to 10,000 instances of undo or redo. Cassies also offers 14 different themes and backgrounds, and you can save an unfinished level and continue playing anytime you want.
