Soko-ban is the official Coco version of the popular cross-platform hit. There were even text versions of it for OS-9, with the exact same mazes (and the ability to add your own). The object of the game is push the treasures around the maze until you get them all lined up in the treasure room (marked by the circles). Since you can only push one at a time, and not around corners, it takes a lot of strategy and planning (especially at later levels) to do so. It also records how long it took you to solve each level, and how many moves and pushes it took you.
This is another "fat binary" cartridge, in that it had special options for the Coco 3 if you played it on that platform. It also holds the record for most sub-licensing to get a game to market, as you can see from the first intro screen.
