Sudoku is a great teaching tool for building students' critical thinking skills. Sudoku trains students to work together to solve problems and learn to differentiate between relevant and irrelevant information. These skills are necessary for rational problem-solving.

This myViewBoard Original Content contains 4 Sudoku puzzles: Easy, Medium, Hard and Expert. It's not actually about math; it’s about number-placement puzzle.

"Sudoku is a very friendly kind of puzzle," says Thomas Snyder, PhD, a U.S. and world sudoku champion. "You don’t have to come to it with any sort of knowledge beforehand — it's not like a crossword where you have to know trivia."


Sudoku (数独 sūdoku, digit-single) (/suːˈdoʊkuː/, /-ˈdɒk-/, /sə-/, originally called Number Place) is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution. [1]

  • Drag the number to the desired cell.
  • Move the "Answer" textbox to view the solution.
