Your guide to Calcudoku
Take a moment with Calcudoku before moving to another game. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Choose a clear next step rather than rushing through the instructions. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
Twelve puzzles with addition, multiplication, subtraction and singleton cages.
Something to practise
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Notice the feedback after each input.
The objective of a round
Fill a 4×4 Latin square and satisfy every cage arithmetic target. Use the instructions to see which actions move you towards it. Return to the instructions when a step is unclear.
How to proceed
- Select a square and enter 1–4.
- Combine all cage digits using its shown operation.
- Subtraction uses the absolute difference.
- 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. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
An example before you play
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. Look for the relevant detail.
Avoid this misunderstanding
A correct cage total does not permit duplicate digits in a row. Compare the situation with the worked example. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
