From Nikoli, the Japanese puzzle company that created the sudoku craze, comesa title that starts at hard and goes to a level of difficulty not seen in anyprevious books.

Sudoku fans will welcome this bright new twist to the popular puzzles! Every one of these ingenious creations--from "Bold X" to "Rainbow Up"--makes colors and patterns part of the solving fun. And although each puzzle maintains the normal 9x9 grid and follows the basic rules of the game, every style adds an additional restriction to intensify the challenge. In "Worms," for example, swirly, squirmy shapes fill the grids; the numbers increase as you work your way from head to tail. "Even/Odd" features squares in two colors, depending on whether the number to fill it is even or odd. And in "Positional Board," no two of the red squares can be the same number. They're all lots of fun!

Just when you thought it was safe to pick up a pencil Killer Su Doku is based on the original Su Doku grid, with the same rules and numbers—1 to 9—but with an added deadly twist. This time there is an element of arithmetic involved and there are few, if any, clues. The aim is to not only complete every row, column, and cube so that it contains the digits 1 to 9, but to also fill in the outlined cubes so they add up to the same number. Hints to solve the puzzle are hidden in the joined squares where only one combination of numbers applies. In the case of joined squares, if the printed number is 3, it should be 1 and 2 that go into the squares. Likewise, in the case of three joined squares, if the printed number is 6, the only combination possible is 1, 2, and 3. To add one final fiendish level, each puzzle also has a time worked out by its Japanese creators so you can try to beat the clock.
