An introduction to playing Calcudoku

Take a moment with Calcudoku before moving to another game. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Look at what changes after your first action. Choose a comfortable screen position before beginning. Keep the game area visible while you use its controls.

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

Practice beyond the first move

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Notice the feedback after each input.

Your objective

Fill a 4×4 Latin square and satisfy every cage arithmetic target. An attractive position is not enough unless the goal is met. Review the board or playing area as it changes.

The order of play

  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.

The controls to know

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. A new-round button replaces the current round.

Put the rules into context

A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.

Where a round can go wrong

A correct cage total does not permit duplicate digits in a row. Check the rule before repeating the action. 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.
