Kakuro To Go

In 2005, Michael Mepham's Sudoku to Go proved itself to be the commuter and traveler's best friend - a game that provides hours of entertainment, requires nothing more than a pencil and a brain, and is collected in a book that fits in your coat pocket.

Now Overlook brings you the first compact edition of the next wave of international puzzle craze: Kakuro to Go.

Kakuro is a hybrid of logic puzzle and number crossword. The clues are the sums of the digits in each block of numbers. All you have to do is work out where the digits from one to nine should go.
