Something to practise
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. Refer to the controls when needed.
The objective of a round
Fill a 4×4 Latin square and satisfy every cage arithmetic target. Keep that objective in view throughout the round. Keep the controls in easy reach.
Step by step
- Select a square and enter 1–4.
- Combine all cage digits using its shown operation.
- Subtraction uses the absolute difference.

Input guidance
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. Use one clear input at a time.
Work through an example
A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Apply the same reasoning to the position in your own round. Check the stated objective.
Avoid this misunderstanding
A correct cage total does not permit duplicate digits in a row. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
