Xmas Mahjong is a mahjong connect game with a Christmas tile set: link two matching tiles with an unobstructed path that turns no more than twice.
Hint and shuffle buttons are there for when a board looks deadlocked, and levels continue for as long as you keep clearing them.
Two matching tiles can be linked if a clear path exists between them turning no more than twice, with nothing blocking it.
Nothing is stacked — the constraint is the route between tiles rather than what's on top of them.
Yes — tap two matching tiles. Nothing to install.
