Traditionally, the classic game Shut the Box (also known as Tric-Trac or Canoga) is played using dice. In this updated take on the classic, two dice are rolled (behind the scenes) and the sum is displayed at the top of the screen. A box, consisting of tiles numbered 1 to 9, is displayed and each tile may be recessed to cover that number.

The player must close as many tiles as they wish to total the sum; e.g., if the dice show a total of 6 then any of the following combination of tiles could be covered: (6), (5,1), (4,2), (3,2,1).

The game is lost when none of the remaining tiles are valid for the number displayed. When all nine numbers are covered, the player wins!
