Read before your next round of Calcudoku
Start Calcudoku by looking at the playing area and its controls. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Choose a clear next step rather than rushing through the instructions. Read the objective before making your first input. Check the relevant rule before repeating a move.
Twelve puzzles with addition, multiplication, subtraction and singleton cages.
Practice with a purpose
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. Make the next step deliberately.
What you are aiming for
Fill a 4×4 Latin square and satisfy every cage arithmetic target. The feedback beside the game helps you follow the round. Notice how the game responds to your input.
The playing sequence
- 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. Read a button’s label before selecting it. A new-round button replaces the current round.
One way to understand the rules
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.
Pay attention to this rule
A correct cage total does not permit duplicate digits in a row. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
