Then HIDOKU is the game for you It's a logic number puzzle game which develops your problem solving skills and reasoning. The rules are quite simple: fill in the grid by creating a path of consecutive numbers. Start with 1, end with whatever the largest number in a puzzle is. Consecutive numbers must be connected either horizontally, vertically or diagonally. In some of the puzzles in this book you must fill in close to 300 numbers All in all, there are 200 puzzles in 6 levels of difficulty, so there should be something for everyone's taste. Yes, there are even puzzles labeled "INSANE" Most puzzles are right in between - neither too simple nor too difficult, just moderately tough and challenging but solvable.
