Exercise your brain (and have fun) doing Sudokus. Crayola® Dry-Erase Markers make it easy to create and solve your own fascinating puzzles.
Sudoku puzzles, designed in 1979 by architect and puzzle constructor Howard Garns, are popular all over the world. After you do one, you will know why. These puzzles challenge you to apply logic and reasoning, not your mathematical ability.
Each puzzle has only one solution. To complete any puzzle, each row (there are 9), each column (9 again), and each box of 3 x 3 cells (9 cells) must contain the numerals 1, 2, 3, 4, 5, 6, 7, 8, 9 without any repeats in a row, column, or box.
Each puzzle has some digits already printed in the cells. The number and placement of these clues affect the level of the puzzle’s difficulty. Use samples from a book or online to start. For a real challenge, create your own puzzles (hint: start with one that’s finished and erase several numerals).
Draw your Sudoku puzzle with a Crayola Dry-Erase Marker on a dry-erase board. Make 9 rows of 9 columns.
