About Doubloom: Number Merge
Swipe to slide all tiles. Two equal numbers that meet merge into one tile of double value, and every level gives you goals such as creating a certain tile, reaching a score or clearing obstacles, often within a limited number of moves. Earn up to three stars on each level.
Travel through ten island worlds, each with its own look and twists like rocks to crack, frozen tiles to shatter and locked cells to open. Reach big tile values and the buildings on the map rise one by one, from paths and cottages to windmills, lighthouses and castles.
