A walkthrough of the rules
- 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.
Making selections and moves
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. Use one clear input at a time.
Try this example
A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Compare this with the rule that governs the move. Choose a deliberate next step.
A common point of confusion
A correct cage total does not permit duplicate digits in a row. Compare the situation with the worked example. 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.
