Lost Sock Games has released their second game for the Macintosh platform, Kakuro Quest. In partnership with Macgamestore.com, the game is now available as a digital download through the popular Macintosh game store for US$19.95. “Kakuro Quest puzzles resemble crosswords or Cross Sums which use numbers instead of words. The aim of the game is to fill all the blank squares in the grid with only the numbers 1-9 so that the numbers you enter add up to the corresponding clues. When the grid is filled, the puzzle is complete.” A free demo is also available for download.
