  2. Each square is its row header times its column header. Some headers and products are shown.
  3. Tap a square and type a number (keyboard or the on-screen pad). Arrow keys move between squares.
  4. Find every header and every product. Hint shows the next number you can work out and the sum that gives it.

A worked example

The column headed 4 contains a 28. So the row header times 4 is 28 — the row header is 28 ÷ 4 = 7.

That row also contains a 63, in an unknown column. So 7 times the column header is 63 — the column header is 63 ÷ 7 = 9.
