How to play Calcudoku

Bring your attention to one round of Calcudoku. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Keep the game area visible while you use its controls. Compare the starting position with the example in the Guide. Look at what changes after your first action.

Twelve puzzles with addition, multiplication, subtraction and singleton cages.

A careful first round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Refer to the controls when needed.

Your goal

Fill a 4×4 Latin square and satisfy every cage arithmetic target. The feedback beside the game helps you follow the round. Keep the controls in easy reach.

Step by step

  1. Select a square and enter 1–4.
  2. Combine all cage digits using its shown operation.
  3. Subtraction uses the absolute difference.
  4. Check puzzle verifies the entire grid.

Controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Use one clear input at a time.

A useful example

A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Apply the same reasoning to the position in your own round. Keep the controls nearby.

Watch out for this

A correct cage total does not permit duplicate digits in a row. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
