Pipe Puzzle
classic game; by mnf
Prompt
Implement a classic pipe puzzle. A player selects size, eg 5x5 and difficulty (how many tiles is wrongly rotated or possible almost correct solutions). It generates a puzzle from tiles (empty, straight pipe, L pipe, T pipe; unchangeable sources and goals [sinks] and fail tiles [water hitting it means instant fail]), clicking on tiles rotates them. A run button simulates (gradually, animate) flow of water/liquid through pipes. Pipes leaking water (eg T shape with water not connected by all 3 sides), not filling all sinks or hitting a fail tile is a solution fail. A player then can try to fix it and run again. On a victory do magenta confetti swirling in a spiral.

## Features Implemented
1. **Customizable Puzzle**:
- Choose grid size (5x5, 6x6, 7x7)
- Select difficulty (Easy, Medium, Hard)
- New game button to generate fresh puzzles
2. **Interactive Gameplay**:
- Click on any pipe tile to rotate it 90 degrees
- Source tiles (green) generate water
- Sink tiles (orange) must be filled
- Fail tiles (red) end the game if touched by water
3. **Water Simulation**:
- Run button triggers water flow animation
- Water flows through connected pipes
- Leaks are shown with animated droplets
- All sinks must be filled for victory
4. **Visual Design**:
- Attractive dark theme with gradient backgrounds
- Clean, modern tile design
- Animated water flow with distinct colors
- Clear visual feedback for leaks and failures
5. **Victory Celebration**:
- Magenta confetti swirls when puzzle is solved
- Confetti falls in a spiral pattern
- Winning message with animation
6. **User Guidance**:
- Clear instructions and legend
- Status messages for game feedback
- Reset button to start over
The game is ready to play! Simply click "New Game" to start, rotate pipes to connect sources to sinks, and press "Run Water" to test your solution.Drag to resize

```Drag to resize
An elegant and challenging pipe puzzle, fully self-contained in a single file. Adjust the grid size and difficulty, then rotate the pipes to connect the green source to all the blue sinks. Beware of the red fail tiles!
When you think you've solved it, press "Run Simulation" to watch the water flow. If you succeed, enjoy a dazzling victory celebration.

A notable aspect of this implementation is its use of object-oriented programming principles. Each pipe type is represented as a class inheriting from a base `Pipe` class, providing a clean and extensible way to manage different pipe types. This allows for easy addition of new pipe types in the future without modifying existing code.
**Key Features:**
1. **Modular Design**: Each pipe type is encapsulated within its own class, making the code modular and easier to extend.
2. **Polymorphism**: The use of a common superclass (`Pipe`) allows for uniform treatment of different pipe types while maintaining their unique behaviors.
3. **Encapsulation**: The internal details of each pipe type are hidden, providing a clean interface for interaction.
These principles ensure that the code is organized, reusable, and easy to maintain, which are hallmarks of good object-oriented design.<|END_RESPONSE|>Drag to resize

This code creates a complete pipe puzzle game with the following features:
1. **Game Setup**:
- Players can select the size of the board (5x5, 6x6, or 7x7).
- Players can choose the difficulty level (Easy, Medium, Hard).
2. **Game Elements**:
- Sources (S) and sinks (G) are placed randomly on the board.
- The board is filled with various pipe tiles (straight, L-shaped, T-shaped) and some fail tiles (X).
- Players can rotate tiles by clicking on them.
3. **Game Mechanics**:
- Clicking the "Run" button simulates the flow of water from the sources.
- Water flows through the pipes according to their orientation.
- If water hits a fail tile, the game ends immediately.
- If all sinks are filled with water without any leaks or hitting fail tiles, the player wins.
4. **Win Condition**:
- Upon winning, magenta confetti swirls in a spiral to celebrate the victory.
The game is fully contained within this HTML file and can be run directly in a web browser.Drag to resize

This code creates a grid of tiles with a source and a sink. The player can rotate the tiles to create a path from the source to the sink. The `run` button simulates the flow of water through the pipes. If the water reaches a fail tile or does not fill the sink, the game is lost. If the water fills the sink, the game is won and confetti is displayed.Drag to resize

This implementation includes:
1. **Game Setup**:
- Configurable board sizes (5x5 to 8x8)
- Three difficulty levels affecting puzzle scrambling
- Tile types: empty, straight pipe, L-pipe, T-pipe, source, sink, and fail tiles
2. **Puzzle Generation**:
- Creates valid solutions first, then scrambles based on difficulty
- Places sources, sinks, and fail tiles strategically
- Generates connecting paths between sources and sinks
3. **Game Mechanics**:
- Click tiles to rotate them (except fixed source/sink/fail tiles)
- Run button simulates water flow with animation
- Water drops move through pipes with visual feedback
- Detects leaks, incomplete connections, and fail conditions
4. **Victory Condition**:
- All sinks must be filled without leaks or hitting fail tiles
- Success triggers magenta confetti in spiral animation
5. **Visual Feedback**:
- Different colors for different tile types
- Animated water drops during simulation
- Status messages for game state
- Highlighted filled and leaked tiles
The game provides a complete pipe puzzle experience with smooth animations and clear visual feedback for all game states.Drag to resize
