Here's a new website to do bughouse puzzles: https://bughouse.ca/

We developed an engine to generate bughouse puzzles and a website where you can improve at bughouse by doing puzzles.
The puzzles require interaction with your partner, e.g. you can ask or give them pieces, to simulate a real game.
Come and register to get better at bughouse: bughouse.ca/

We hope you like it. We plan to add new kinds of puzzles in the future and new features. Suggestions are also welcomed!

Very nice project! As someone who's tried these puzzles, I can say that they're an excellent step forward and I hope to see more bughouse projects like this to grow the game!
