- The top puzzle is a 6x6 grid with numbers 1-6. Each row and column must contain each number exactly once, and the grid is divided into regions with operations that must equal the target number shown.
- The bottom puzzle is also a 6x6 grid with the same rules: each row and column contains 1-6 exactly once, and regions have operations that must match their target.
- Solve by applying logic: start with regions that have only one possible combination (e.g., “2÷” in two cells can only be 2 and 1; “6×” in two cells can only be 3 and 2 or 6 and 1).
- Fill in forced entries first—cells where only one number fits based on row/column constraints and region operation.
- Use process of elimination: if a number appears in a row or column, it cannot appear again in that row or column.
- For multiplication and division regions, consider factor pairs within 1–6; for addition and subtraction, consider all combinations that sum to or differ by the target.
- Continue iteratively: as cells are filled, update possibilities for neighboring cells and regions until the entire grid is complete.
