Wildcard color control
The Rainbow Bubble matches any color it touches, making it ideal when the board is fragmented into small, mismatched clusters.
- Bridge colors: Use Rainbow to connect two separate clusters into a single, clearable group.
- Patch weak links: Repair a nearly-formed chain so your next basic bubble shot can trigger a large drop.
- Endgame fixer: When few colors remain, a Rainbow shot often clears the final awkward bubbles in a single move.
