Calcudoku: what to know before playing
Read the aim of Calcudoku, then make your first move. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Keep the game area visible while you use its controls. Keep the instructions close while learning this activity. Check the relevant rule before repeating a move.
Twelve puzzles with addition, multiplication, subtraction and singleton cages.
A small practice goal
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. Keep the objective visible.
What you need to achieve
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.
Start here and follow along
- 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. Use the control method described here for this activity. Return to the rules if the result is unexpected.
Follow the example
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. Read the matching step again.
Keep this in mind
A correct cage total does not permit duplicate digits in a row. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
