How to play Calcudoku
Try Calcudoku at your own pace and keep its objective in view. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Look at what changes after your first action. Treat the first round as a chance to learn the controls. Check the relevant rule before repeating a move.
Twelve puzzles with addition, multiplication, subtraction and singleton cages.
Keep the aim in sight
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
Your goal
Fill a 4×4 Latin square and satisfy every cage arithmetic target. Use the instructions to see which actions move you towards it. Notice how the game responds to your input.
Step by step
- 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.
Controls
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. Return to the rules if the result is unexpected.
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.
Watch out for this
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.
