Puzzle No. 501 & 502 – Killer Sudoku & Extra Region Sudoku [Daily League]

Now that I’ve posted my 500th puzzle, I am sharing the Sudoku I contributed to the Daily League last Saturday, along with the Sudoku I’m contributing for it today. I didn’t post the Killer last week on my blog because I wanted the space saved for the special puzzle.

Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay.

Common Rules – Follow regular Sudoku rules.

For Killer The number in the top-left corner of a dotted cage is equal to the sum of this cage’s digits. No digit can repeat within a cage.

For Extra Regions – Each group of nine grey cells must also contain the digits 1 to 9.

Enjoy!

Puzzle No. 491 : Killer Sudoku [Daily League]

Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay (though I’m not certain whether this is too late to be put up today).

I’m sorry dearest readers, I think I’ll have to skip an explanation of why I’m inactive on my blog right now for later. There’s just too many plans right now, that all seem to end around May, and if it all goes as planned, you’ll see at least some of the reasons why I’ve been too busy to post here.

Anyway, here’s a Killer Sudoku that was used for the Polish Sudoku Championship qualifiers. These qualifiers were open to International solvers online, so I think many solvers would have seen this already. I still think it’s nice enough to put it up for those of you who haven’t.

Rules – Follow Classic Sudoku rules.
Additionally, the value on the top-left corner of a dotted cage is equal to the sum of the digits in the cage. No digit can repeat within a cage.Enjoy!
