The gameplay of Suika Game is simple but strategic. Players will drop different types of fruits into a rectangular box (like a pit), using free-fall physics. When two fruits of the same kind touch each other, they will merge into a larger fruit according to a specific evolutionary chain. For example, the sequence is cherry → strawberry → grape → orange → apple → watermelon, with watermelon (Suika) being the largest.

The goal of the game is to:

• Combine fruits to form larger fruits to score higher points.
• Avoid overflowing the fruit box — if a fruit reaches the top edge, the game is over.
