Sudoku Calendars

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!

Obsessed sudoku fans know that the newspaper puzzles just aren’t enough to feed their solving addiction. But they don’t have to worry, because they can pull out as many pages as they need from this sudoku collection and take them along to work on whenever the urge hits. It features nearly 160 puzzles to choose from, all 9x9 and of medium difficulty. But newcomers who want to plunge in will find all the tips, hints, and instructions they need up front to begin—including advice on eliminating squares using hidden pairs in rows and columns. Of course, all the solutions are right there on the back of the page, so you can check (or cheat) when needed.
