Goal
Fill in the blank boxes by moving your mouse over each square and clicking when you see the number you want.
Rules
Each column and row (regions) must include the numbers 1 through 9. Also, each 3×3 box (cage) within the large box must have the numbers 1 through 9. The numbers cannot repeat.
Tips
- Use process of elimination to determine what numbers go in which box- No region can contain any duplicate digits. In a Roodoku region each digit appears exactly once. For example, if a digit appears in a row, it cannot be in any other cell in the row.
