    • Just FYI, Show HN isn't meant for blog posts. It's for things that can be interacted with. See: https://news.ycombinator.com/showhn.html You might want to edit the title.

    • This is great, I love rush hour. Is there an web based version of the game where I can try some of these generated puzzles?

  • Which search algorithm and solver is used

    • What solvers is he using? Is it really just some sort of simulated annealing? I would have expected A* search at a first glance.

    • Btw, if you like Rush Hour, I highly recommend Antivirus (terrible name for Googling) by Smart Games [1]. The pieces come in 9 distinct shapes along with 2 wall pieces, which…

  • Un-block Me solver
