"## How to play 1. **Goal**: Connect all points of the same color two by two, and the connecting lines cannot cross, and finally fill the entire grid. 2. **Operation**: Press and hold a colored point with your finger and drag it to another point of the same color to form a connecting line. 3. **Restrictions**: - Lines cannot cross or overlap. - All grids must be filled to pass the level. 4. **Level**: The points and color combinations of each level are different, and the difficulty gradually increases. Some levels contain obstacles. ## Main functions - **Level System**: A total of 50 carefully designed levels, supporting difficulty selection (easy/medium/hard). Each level has a star rating and best time record. - **Dynamic main interface**: The main interface has a variety of dynamic backgrounds such as particles, bubbles, and energy waves. The four main buttons have different styles and rich animations. - **Game Interface**: Customize GameView to support smooth touch connection, undo, reset, prompts, victory detection and other interactions. - **Level Selection**: The level page displays all levels in the form of a card grid, showing clearance status, star rating, and best time, and supports click to jump. - **Leaderboard**: The local leaderboard displays the player's clearance progress, star rating, and best results. There are friendly prompts for empty status. - **Settings page**: Supports functions such as vibration, display prompts, auto-save, dark theme, reset progress, about, etc. The interface is simple and animated. - **About Page**: Introduces game information and supports return animation. - **Immersive experience**: Globally transparent status bar and navigation bar, white status bar icons, more modern interface. - **Animation and Beautification**: All main interfaces and game interfaces have rich animations, and buttons, cards, stars, etc. all have dynamic feedback. ## Highlights - Pure Java implementation, strong compatibility and excellent performance. - Beautiful UI, delicate animation, and smooth interaction. - The level generation algorithm ensures that each level must have a solution, supporting obstacles and multiple difficulties. - Data is saved locally and supports progress reset and statistics. - Suitable for leisure and entertainment, thinking exercise, and parent-child interaction.
