Educator's Review: This version of sudoku is a logic puzzle where players have to place numbers around a grid so that they make sense according to the mathematical operations in the grid. Numbers have to show up once in each column and row, while still making sure the numbers add up correctly, so a placement that seems correct at first may turn out to be wrong. Players have to keep an open mind throughout the game and be flexible with their answers.
Please Note: Although this is a numbers-based game and does involve math, it is primarily a logic game that students who are normally good at math might have a hard time with.
