## How to play

1. **Goal**: Eliminate all blocks with the same pattern.
2. **Rules**:
- Only two blocks with the same pattern can be connected, and the connection line does not exceed two turns (i.e. within three straight lines).
- Only two blocks can be selected at a time. If they can be connected, they will be eliminated. Otherwise, they will be selected again.
- The board will be automatically shuffled when there is nothing left to eliminate, ensuring no dead ends.
3. **Score**: Each pair is scored successfully, and the total score can be viewed after completing the level or the normal mode board.
4. **Time**: There is a countdown for each game. When the time runs out, the game will fail.
