How to interact with the game
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. 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. Your next round may have a different position, so inspect it before acting. Keep the game’s format in mind.
A useful caution
A correct cage total does not permit duplicate digits in a row. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
