Click or touch a ball to start a chain. Drag through balls of
|
||||
the same color to link them together. Drag back to the previous
|
||||
ball to undo the last link. Release to finish: chains of fewer
|
||||
than the minimum vanish; chains with enough balls clear all
|
||||
linked balls (score: 10 × length²). If the entry gets blocked
|
||||
and a new ball cannot drop in, the run ends—restart to try
|
||||
again.
