Available as a column in the New York Times puzzle section, KenKen is a Japanese math grid game that has been compared to Sudoko. The goal is to fill in a grid while making sure the conditions for each box are met. This electronic handheld version contains an "endless supply" of puzzles, with instant correction capability and an LCD touch screen. It is a great way practice math facts, although we were less than impressed by the quality of the touch screen.
