and become a patron

This website is free to use, but the servers to run the website and calculate the puzzles aren't. I'm relying on the support of sponsors, patrons, and some advertising banners to cover these costs. By becoming a patron, you help to keep these servers running.

I'm also working very hard on further improvements of the site. The following features are planned for the future:

  • New puzzle types
  • New puzzle modes
  • Improved rating system
  • Improved solution view
  • Features to keep track of your progress and improvement over time
  • And more
By becoming a patron, you help researching and developing these exciting new features.

Thanks a lot for your support!
