📖 Merge Lab Guide: How to Play, Tips & Strategy

Merge Lab replaces falling physics with a tactical 6×6 board. Place the next numbered orb in an empty cell; every orthogonally connected group of equal levels collapses into one higher orb and can immediately cascade again.

1. Place the new orb inside a group, not at its edge, so the upgraded orb stays well connected.
2. Save the Hammer for an isolated low-level orb that blocks a valuable route.
3. Shuffle is strongest on a nearly full board because it can reconnect several pairs at once.
