Yes, but we must admit that this guy, Mister Rohanrao Blogspot, doesn't look very serious ! Does anybody know him ?


I'm not sure.. I think he's some foreigner...

Should've kept "no" and "does not matter" as two separate options in the poll, now the people who wanted it might get out voted by people to whom it didn't matter. Of course this is in hindsight, it just struck me.

Hope to participate in this test. Is it possible to mark the arrows in a paler colour in Arrows Battle Sudoku?

Thank you,

David McNeill.

As there is a big majority in the poll who said that it were not better to have marked diagonal in the anti-diagonal sudoku (or it does not matter) , I'll not add them.
Sorry for the 7 people who voted for marked diagonals in the anti-diagonal sudoku, I hope you'll have fun solving this grid despite that.

I just find it handier to know any marked diagonal means different digits.

I got through this one by a complex work through of where the 9s can and can't be, first of all I'd suggest you put the 8 in R1C1, as the 5-7 pair take up the below row and the 9 in the middle omits a 9 in either of the main diagonals. After that, either just look at the 9s and think hard about the possibilities with the queen rule, or find another way and tell me as well

This grid is perhaps a bit hard for the instructions booklet. Prasanna is right, you must study the 9's and try to find a contradiction. I think it's the only possibility to crack this grid.
For example, if you try to put a 9 in R6C1, then you have a 9 in R9C3 (only option is that box), then it has to be in R8C9 (only option in this row), then in R4C7 and then you cannot place a 9 in column 8.

So you know that R6C1 is not a 9, and then it becomes easier to finish the grid.

This is easily the longest I've stayed in the top 10 of an LMI test. That might be more to do with them being extended to Monday though

Funnily enough my most significant steps in improving in Sudoku tests have come after I've started concentrating on puzzles. I'll just keep doing what I've been doing.
