Last Sunday, South Korea hosted the Asian Sudoku Championship in Seoul, which included a set of classic Sudokus that I wrote.
These originally came out of practicing my Sudoku construction skills by writing a puzzle a day for a long week early last year. It’s still a hit-or-miss process for me, but I think there were some nice ones. Solve on PZV (a b c d e f g h i) or find the set below.
In other news, don’t forget to take part in Puzzle Ramayan at LMI this weekend: A set of easyish classics and region puzzles that I prepared, including some instructionless variants.
Took me a bit longer this year, but here’s my set for the 24 hours from April. I took a bit of a different approach this year, with four puzzles each of six more or less standard puzzle types. My hope was to make the round a bit more approachable than in previous years, though this may have been taking it a bit far. But I think the round worked out fine in the contest.

I made a couple of puzzles for the Polish qualifiers back in February. I previously posted two more puzzles which didn’t make it: Angle Loop, Doubleback.
One Minesweeper puzzle (with an unknown number of mines). The kind of puzzle that just feels too trivial when constructing, although in the end I think it’s quite ok.
One Pentominous, with the obvious PL theme.
Finally a small an tricky Checkered Fillomino.
This year’s 24 hour puzzle marathon is just over. Thanks to the organizers, authors and participants for a great weekend. I contributed a round again. It turned out a little less polished and balanced than last year’s, but there’s a couple of nice puzzles in there. Puzzles below, or grab a copy of the booklet.
I contributed one round of puzzles to this year’s 24 hour puzzle marathon in Budapest. Solvers had 100 minutes time, with a target of roughly 800 out of 1000 points for the best solvers. You can download the full booklet, or go through them individually (with a bit of commentary) below.
