Watermelon, a physics-based, logic-puzzle game that originated in Japan that's often referred to as Suika or the Suika Watermelon Game, tasks the player with merging fruits in a clear rectangular container. It is similar to the tile-merging 2048 game but poses a lot more difficulties because various fruits bounce around inside a container that has limited space. If the player piles up the fruit too much, a red flashing warning line appears along the front edge. If they fail to keep the fruit in the container, the game ends.
Gameplay isn't complex. As with cube versions of 2048, the player receives a shape and drops it in the container. The game features anthropomorphic bananas, blueberries, cherries, coconuts, melon, oranges, pears, pineapples, plums and strawberries. They must combine two identical types of whole fruit to make a new one. For example, they might combine two blueberries to make a cherry and two cherries to make a strawberry. Their ultimate goal is to combine all the fruit to create a watermelon.
Watermelon provides the player with a hint before the next fruit drops. It displays the next option at the upper-right corner. It also gives the player a white vertical targeting line to help them direct each fruit drop.
