: Each level has a specific score or tile-count requirement you must meet within a limited number of moves or time.
: Success in the puzzle stages earns you stars or points used to unlock "Stash" items in the gallery.

: Clearing tiles at the bottom of the board creates more movement and "shuffling" for tiles above, which often leads to automatic chain reactions and larger clusters.
