Interesting that the time standards are so high for this puzzle: there didn’t seem to be any hard deductions in this puzzle (the hardest I found was a hidden pair). Not that I got anywhere close to GM time, but that’s due to me being terrible at sudoku.
Nice theme!
It is possible our testers had some unusual times, but what I really expect is that the solution path is fairly narrow so it just takes a longer time to get to the solution than you might expect based on step difficulty.
6:44.Ah ! Made GM time by a second.I agree with the previous comment about the time standards being high.The sudoku wasn’t that hard.
But, it maybe because I used uniqueness twice to get to my time and the testers don’t get to use that.
Nice sudoku .
