To play Watermelon Balls - Connect Them All, use your mouse to drag and merge identical fruit balls that appear on the screen, such as apple balls, orange balls, and strawberry balls. When two identical fruit balls merge, they transform into a higher-level fruit ball. Each successful combination increases the size and maturity of the fruit ball, earning you more points.

The goal is to continue merging fruits until you create the ultimate giant watermelon ball. The game challenges you to consider the position and timing of each merge carefully to make the best use of limited space.

As you progress, the levels become increasingly difficult, requiring greater strategy and skill. Compete with other players for high scores, climb the rankings, and showcase your synthesis expertise!
