Dear sudoku and puzzle friends,

we hope that you are enjoying the World Sudoku+Puzzle Convention 2021 and having fun with our sudoku, puzzles, or interviews.

As we wanted to give the essence of the championship to those who do not attend it every year, we decided to keep the whole event free. More than a thousand registered players proved to us that this was a good decision, and our puzzling community can benefit from that in the future.

However, you may have noticed how much work has been done in a few months to prepare for such an event. This is why we want to kindly ask you for a small donation so that we can reward the effort and time of the puzzle authors and organizers who volunteered in their free time and spent hundreds of hours creating, re-drawing, testing the puzzles, and preparing the side events.

You can use PayPal or the Buy Me a Coffee platform for the donation. We will be happy for any amount of money and that will be used for the winner‘s prizes, author‘s rewards, and extension of website capacity.

Thank you very much and enjoy the rest of the event!

Quick post about event Wrap-up:

- As updated before, all rounds can now be done unofficially.
- If you do not want to do that competitively, all rounds can now be downloaded on the progress page, with solutions on the right. Those who want all time trials in one PDF can find that in the Time Trials topic.
- We have posted Solution Booklets for the bonus rounds. We will soon add notes below these to keep track of any puzzle issues of the specific rounds that may be relevant to people who go back and try the puzzles.
- We will try to post solution booklets for the main competition rounds by the end of the week. We may not post solutions for Time Trials, as we don't really have them ready. If one or more of the participants wishes to volunteer solution images or PDFs or penpa links (like IHNN did for the Time Trial PDF) we will happily compile that and upload it in some relevant section. We will at least try to put up author credits for specific puzzles regardless of this.
- The donations page is still active and we plan to keep it active for a week, just in case any of the earlier event participants haven't seen it yet as they haven't revisited the site.
- The only other matter we believe is left to resolve is the posting of the Trivia game content, which will happen soon.
