Coordinates for a location will appear and you have to click on the correct location on the grid. The game is a race against time, and you must stock all 20 bottles quickly in order to be able to open the store on time.

Maze Game

To play the Maze Game, read the instructions and then click on the “Activity” tab along the top. Type coordinates into the X and Y text boxes at the bottom and click the “Go” button to move the robot towards the target location. Be careful that the path of your coordinates does go through a mine. Try checking “yes” at the top to randomize the position of the robot and the target location to make the game more challenging.
