Key is a collectible item used to unlock Crates during gameplay.
Keys appear only in levels that contain Crates and behave similarly to regular matchable items. There are 6 different Key colors, each matching the colors of the fruit items on the board.
Because Keys act like normal items, players can:
Match 3 or more Keys of the same color
Include Keys in regular matches
Combine Keys to create special items
When matched, Keys contribute toward unlocking Crates, helping players clear blocked areas and progress through the level.
Since Keys interact naturally with the board mechanics, they can also participate in chain reactions, cascades, and special item combinations, creating additional strategic opportunities during gameplay.
