Calcudoku: a guide for your next round

Open Calcudoku, check the instructions and begin a round. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Check the relevant rule before repeating a move. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.

A small practice goal

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.

Understand the aim

Fill a 4×4 Latin square and satisfy every cage arithmetic target. Use the instructions to see which actions move you towards it. Review the board or playing area as it changes.

Making your moves

  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.

Keyboard and screen controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Check any mode label before starting.

A useful example

A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Focus on why the action is allowed, not only its outcome. Choose a deliberate next step.

Notice this detail

A correct cage total does not permit duplicate digits in a row. Take a moment to reassess the position before continuing. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
