How a round unfolds
- 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.
Keyboard and screen controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Make sure you are interacting with the game rather than the surrounding page.
Put the rules into context
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. Keep the game’s format in mind.
An important reminder
A correct cage total does not permit duplicate digits in a row. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
