Notice the feedback
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

A useful example
A 0 cell has no loop edge around it; a 3 has exactly three. Apply the same reasoning to the position in your own round. Notice the change in the playing area.
