Strategy for a nearly full tray
Start by counting pairs. If two clownfish are already in the tray, search the exposed bubbles for a third before selecting a new creature type. A completed triple creates three empty spaces at once.
When no immediate match is available, prefer a bubble that reveals one of your existing tray types. The small stack counter shows when several tiles remain below a bubble.
When to use Rescue 3
Rescue is strongest when the tray contains three unrelated early picks. Move them aside, complete one or two triples, then return the rescued creatures when their partners appear.

The first level uses only a few creature types and a short solution sequence. Use it to learn the bubble layers and automatic triple clear.
Every level is generated from a known clearing order, so there is always a solution.
