This is the only portable game that comes in form of a suitcase for your near and far travels with a pet companion. It contains two games - “dog sudoku expert rainbow” (which can be removed from the case and used separately at home) and another puzzle “18” where the treats are hidden under cylinders and hats that move in the tracks. Also, this game features 2 drawers that need to be open by pulling on the rope in order to reach the prize. The level of difficulty can be controlled by adding and removing “hats” and “cylinders” so the dog is gradually introduced to its rules. Bon voyage!
