The Grid grows from 7 X 7 to 10 X 12, challenging players to fill the grid to complete the puzzle. The game features unlimited puzzles, a "Quest Mode" via map play with increasing difficulty, and the ability to print out puzzles to solve them on paper. Kakuro Quest is available for $20 via Macgamestore.com, and requires Mac OS X 10.2 or later.
