How to Tweak the “Big Watermelon” Cocos Game: Source Files and Score Hacks

Game Overview

The “Big Watermelon” (合成大西瓜) game is a simple, ad‑free mobile game that became popular on Chinese social media. Players tap to drop fruits, collide them, earn points, and see their rank against global players.

Source Structure

The game is built with the Cocos engine and consists of four core files:

index.html

settings.js

project.js

ads.js

These files contain the UI layout, configuration, main game logic, and ad handling respectively.

Modifying the Score

The game loop follows a straightforward sequence: click → collision → scoring → display . To change how points are calculated, you can either adjust the scoring rule or modify the final displayed value. The scoring variable is referenced by the keyword score (or addScore).

In the source you will find a line similar to: a.default.score += this.fruitNumber + 1 Changing the constant 1 to any custom number or to a variable (e.g., extraScore) directly alters the points awarded per fruit:

a.default.score += this.fruitNumber + extraScore

After editing, rebuild or reload the game to see the new scoring behavior.

Other possible “magic‑mod” ideas include forcing the same fruit to drop each round by locating the fruit‑generation code and editing its parameters.

Algorithmic Optimization (Optional)

Beyond manual tweaks, you can treat the game rules as a small optimization problem and train an algorithm to automatically discover high‑scoring strategies, turning the casual game into a testbed for simple AI techniques.
