Try a more deliberate round
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. Use the example to check your reasoning.

Getting comfortable with the controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. Check any mode label before starting.
Put the rules into context
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
