Good night Tom and all. Tatooine Sunset is going to appear in CTC's book (that they are doing through kickstarter), hopefully along with a brand new puzzle from me (I've been working on that this week, thus the lack of new forum posts).

Then the cover sets also contain exactly N true placements, and since the cover sets cover all of the base sets, every placement that is in a cover set but not in a base set must be false and can be eliminated.Almost every Sudoku technique is a special case of this general formulation:- Hidden single (e.g. Learn basic Sudoku strategies to solve Sudoku puzzles faster.

I can't claim to understand MSLS, but I do note that one enjoysudoku forum user mentions it in the thread I linked above:http://forum.enjoysudoku.com/tatooine-sunset-tatooine-sunrise-t38180.htmlI had a look at what I think is the reference for MSLS.

Finally a 36 naked pair in row 2 (c2 and c7).Now with all of the marked pairs and triples, you should have no problem finishing the puzzle normally.---------------------------------------------------------------We used three MSLSs here. The base sets contain a total of N true placements, one for each truth set.Suppose further that we can find another N pairwise disjoint truth sets called the "cover sets" with the property that every placement that is in one of the base sets is also in one of the cover sets.

The examples from the Tatooine puzzles (we discuss sunset here), as well as Sam's puzzle (as discussed in Reloaded) involve rather large sets of "hidden" digits with multiplicity that somehow need to be squeezed rather tightly into similarly sized sets of cells within the grid, and both the digits and the cells can be hard to see on the face of it. My published puzzles can be found here. Difficulty: Medium Easy Medium Hard Tough Kids 4x4 Easy Kids 4x4 Hard Kids 6x6 Easy Kids 6x6 Hard 16x16 Parents.

This is a combination of UR with Naked/Locked Subsets.We look for two non diagonal cells in a possible UR that have extra candidates. Check that this then gives you a naked single 4 in r6c7, followed by a hidden single 4 in box 4. Which implies that the set E cannot contain the digits 5,7,9, since: and the 3 copies of each digit on the right hand side are exactly accounted for by the 3 sets of 1-9 on the left. Note also that, focusing now only on 5 and 6 in the same columns, that we need to place six digits in total, and there's at most two in r1, at most one in r4, at most two in r6 and at most one in r9, which totals six, so we can eliminate 5 and 6 from the other cells in those rows.After carrying out eliminations from these MSLSs, there is now a hidden single 8 in row 1.

See the picture here: https://i.ibb.co/Lrm7h0T/Tatooine.png.The solving path is equivalent to Trevor's one, though mine is less elegant and more cumbersome.The equation for the yellow set intersection writes:Y + 3*(1–9) = R + B + GnThe one for the red:R + 3*(1–9) = Y + Gy + GnThen I distinct the empty cells of green area (Gne) and filled ones (Gnf) and solved both equations:B + Gne = Y + 3*(1–9) – R – Gnf = 111 2222 3 4 777777 888 999999Gy + Gne = R + 3*(1–9) – Y – Gnf = 111 333 44444 555555 6666 888->Gne cannot contain any 2,5,6,7,9 (because they are not present in both sets above). 5:30.
