A closer look at one example
On one puzzle in this collection, row 1, column 3 has 2 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.
Where a round can go wrong
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
