Now back to this week's Daily League Sudoku. The last week has featured a nice Multiplication Table Sudoku by Seungjae Kwak, an easy Killer Pair Sudoku by Fred Stalder, a challenging but fun Point to the Next Sudoku by Prasanna Seshadri, a very hard Greater than Killer by Bastien Vial-Jaime, a Non-Consecutive Anti-Knight Sudoku by Rishi Puri and a Classic Sudoku by Tom Collyer.
This time I've made a Quad Second Sudoku, which is a twist on the Quad Max Sudoku. As far as I know it's an original variant. I think it changes the solve of a Quad Max enough to make for a fun new variant. For me personally this is my favourite puzzle I have made for the League so far. I think I got the right difficulty with this puzzle compared to some of my earlier puzzles. Hope enjoy it.
Lastly, here are the link to the PDF of Week 6.
Rules for Sudoku
In this Sudoku an arrow points at the second highest digit in the four cells around it. Digits may repeat around an arrow, but the second highest digit is always unique.

I don't think I completely understand the quad rule. If four such squares contain only the three values 1, 5, and 9, then of course the 5 appears only once, but does 9?ReplyDelete
In that situation only 9511 would be a valid digit combination. With 9951 5 would be the third highest digit. When 2 equal for first, the next digit is third.Delete
