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. Refer to the controls when needed.
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. Use one clear input at a time.
Follow the 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. Verify the rule before continuing.
A mistake to avoid
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.
