The First SudokuCon is here!! We are excited to host everyone in Boston, MA and are looking forward to the next three days of puzzling fun! Tickets are still available for access to SudokuCon livestream. Information is here: sudokucon.com

What would a SudokuCon be without a giant interlinked puzzle?! Come along and add a digit or two!

Getting to meet so many members of the sudoku community in one place is a surreal and fun experience - topped only by getting the chance to hobnob with Zack the digit dancing penguin from the zetamath streams!

Wrapping up a successful first day of SudokuCon with a three way livestream solve - with Lucian, ChattyKathy and NellGwyn - all solving on the same grid at the same time!

Day two of SudokuCon is underway - with a panel on sudoku solvers and tools with Rangsk, Sirxemic, and Sven! You can check out the rest of the days schedule here: sudokucon.com/schedule

Next up at SudokuCon is zetamath giving a talk on the Math of Puzzles!

Have you ever wondered how it is for 81 people to solve a sudoku at once? We're finding out at SudokuCon!

For the final Saturday session, we had the treat of listening to three time Sudoku World Champion Thomas Snyder. Competition stories, and tips and tricks to solve like a World Champion!

And SudokuCon 2025 - the first ever!!! - is in the books! Thanks to everyone who was able to join us - either online or in person - and to all the presenters!! This was an unforgettable experience!

With a wrap on SudokuCon 2025, we are starting the planning for next year! With that in mind, we are actively soliciting proposals for a location for SudokuCon 2026. If you're interested and want to weigh in, hop onto the SudokuCon discord (discord.gg/rNNn46aQS2)

Join us in 40 mins at twitch.tv/sudokucon for "Anatomy of a Puzzle" as Malrog tackles a puzzle by Tallcat. Together, they will take a deep dive behind the scenes of the setting process to highlight the quirks and curiosities, and to discuss the good, the bad, and the ugly!
