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!

The perfect marriage of two hot trends! Take a break from your Sudoku solving and brain training to color in the pretty designs decorating each puzzle page. One hundred Sudoku puzzles in easy, medium, and hard difficulty levels offer hours of logic puzzle solving. The added bonus of designs for coloring presents a fun and relaxing way to rest your gray matter while puzzling out the Sudoku grid.

Sudoku puzzles are enhanced with seasonal art and completed with colors rather than numbers. Each book provides simple 6x6 puzzles as well as more challenging 9x9 puzzles to build critical thinking and deductive reasoning skills. Strategies for completing the puzzles and answer keys are provided.
