About Hexa Sudoku
Hexa Sudoku begins with small square Sudoku grids and gradually adds larger boards and sum cages. Fill each row, column and outlined box with every permitted digit exactly once: 1–4 on 4×4, 1–6 on 6×6, and 1–9 on 9×9. Later dotted cages add another condition: their digits must total the number in the corner without repeating. Start with missing digits in a row or box before guessing.

On a 4×4 board, use 1–4 in every row, column and 2×2 box. On 6×6, use 1–6 and 2×3 boxes. The 9×9 board uses 1–9 and 3×3 boxes. Select an empty square and enter a digit. Compare the row, column and box; each number may appear only once in each. When dotted cages appear, also check their corner sum. A digit cannot repeat within one cage even if the row and box would otherwise allow it.
