Dire Str8ts: The Gr8 New Number Logic Puzzle - Softcover

Sudoku no longer satisfies? Try Str8ts, a new type of brain buster that adds the twist of sequential numbering to sudoku. The digits 1-9 are still in play, appearing only once in each row and column, but now black squares break up the action, and each consecutive group of white squares must contain numbers that make up a straight, in any order. Any way you look at it, Str8ts adds up to challenging fun!
