Or solve online (using our beta test of Penpa-Edit tools) For this week, you can just hit the solved button on an honor system if you think you’ve solved it. Range is 1-9.Īnswer String: For the USSQT, the answer strings were a set of rows/columns encountered late in the puzzle. Or solve online (using our beta test of Penpa-Edit tools use tab to alternate between Sudoku = big digits and Number candidate = small entries in the corners of cells.) As “extras” from the first Grandmaster Puzzles construction cycle, it seems fitting to get them both up here now. As I’ve discussed before, the non-consecutive constraint is really powerful and constraining in ways you wouldn’t expect but it always needs some hands-on work to cultivate a fun and approachable puzzle.īoth of these puzzle are probably on the easier end for this test, but both are good representations of the new logic that arises from the variation. But if you’d like an extra hard challenge different from this one, put a single 1 in the lower-left corner and try to solve from there. Using a given presentation that evokes the same kind of bars as up top seemed best and gave the solving properties I wanted. It was from that small set of potential solutions that I crafted this puzzle. But there are a whopping 4 possible solutions with the repeated top boxes and no other bars as here (and 2 of those 4 are trivial copies from a 1-9 to 9-1 swap). Well, it turns out that there are no puzzles possible that have just the 2×2 box shapes in opposite corners as in the second linked puzzle without additional bars elsewhere. And I’ve played with 2×2 box shapes with consecutive bars before too, such as here. This trait pulled it towards the top of my pile of Tight Fit to include here.įor the Consecutive Sudoku, I’ve been doing a fair bit of half consecutive/half non-consecutive exploration recently (such as this earlier GMPuzzles one). The solve was meant to fairly easy, but the sparsity of starting digits here actually leads to a rather large cycle to place two of the highest digits remaining towards the end of the puzzle. With Tight Fit, the diagonal symmetry works well with the added slashes forming their own diagonals parallel to the mirror plane. I went for a lot of less common symmetry types with this test (diagonal or mirror symmetries instead of 180 degree rotational) and both of these themes showcase one of those less common types. Two more from the US Sudoku Qualifying Test in May - both are styles I’ve constructed a lot of in the past and will likely continue to construct a lot of in the future as they are both pretty simple variations that add more properties of the numbers into the logic of sudoku and enrich the solving experience.
