Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.

The controls to know
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. A careful first action helps you become familiar with the layout. Read the example below alongside these instructions.
An example to follow
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Apply the same reasoning to the position in your own round. Check the stated objective.
One detail worth checking
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
