About Sven Codes

Hi, Sven here.

I've spent the last year and a half creating and Sven's SudokuPad. And while I feel we've come along way, there is so much more I would like to do.

If you would like to support my work on these projects, this Patreon is for you.

Support my current work:
- The free web app at
- Further improvements and updates to Sven's SudokuPad mobile and desktop app
- Various related systems and services
- Some tech support I do for Cracking the Cryptic behind the scenes

Support my ongoing projects:
- Support the community with code and services
- Create tools for setters, youtubers and streamers
- Help make more puzzles more visible for our community
- Create videos about my work and how to get the most out of the various tools and services

And finally, ambitious, new projects, such as my planned "Sudoku Stories" interactive puzzle fiction, optical puzzle scanners and puzzle sharing and discovery site.

Hope you've enjoyed the puzzling!

At €200 per month I will launch as an alternative to filtering out only puzzle sites to make links more trustworthy and reliable.
