Calcudoku: learn through an example

Use a short break to learn the rhythm of Calcudoku. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Use the example below to understand a decision. Make your first input carefully and watch the result. Check the relevant rule before repeating a move.

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

Practice with a purpose

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.

What you need to achieve

Fill a 4×4 Latin square and satisfy every cage arithmetic target. The feedback beside the game helps you follow the round. Start with a deliberate move.

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.

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. Look at the feedback after the action.

One way to understand the rules

A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Use the example as a guide rather than a substitute for reading your board. Notice the change in the playing area.

One detail worth checking

A correct cage total does not permit duplicate digits in a row. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
