Bird Chain
Bird Chain fills a jungle canopy with colourful birds and asks for chains: link same-coloured neighbours, and the longer the chain, the louder the score. The flock refills from above, so every clear reshapes the tree.
Long chains need setup — sometimes the right move is a short chain that herds two colour groups together for the next turn.
Tip: chase L-shapes and hooks, not straight lines; bent chains collect across refill columns and survive the drop. Feathered relatives at the bejeweled tag.
