Plan one complete match
Prefer a visible pair with a reachable third fish over three separate singles. Completing a group immediately returns space to the holding bar.
Reveal with purpose
Choose a top fish because you need what is underneath it, not only because it is available.
Keep one recovery slot
Try to leave at least one empty holding space. That margin lets you uncover a needed fish without ending the run.
Learn from the first failure
On a retry, change the earliest questionable tap. Later moves often become easier once the opening order is corrected.
