Your inputs
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. Use one clear input at a time.
Put the rules into context
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Look for the relevant detail.
Check this before moving on
No rectangle may contain two clues or overlap another. Read the feedback to see why an action did not have the expected result. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
