Friday Puzzle #74 - Arrow Sudoku  
Rules: Enter a digit from 1 to 9 into each cell so that no digit repeats in any row, column, or 3x3 region. Digits in the circled cells represent the sum of the digits along the path that each arrow travels. In this puzzle each circled cell has three independent arrows that all sum up to the same total. Digits can repeat within an arrow sum, provided this does not violate the standard sudoku rules.

I enjoyed how this one worked out, some nice logic going on with the multi-arrows. I was glad this didn't steal my thunder ideas-wise with my arrow puzzle though!

I think there's still a lot of exciting arrows idea space to explore so little risk of stealing thunder. Your intersecting cube network was very nice.

Not too tough, but very elegant.

Nice puzzle ...
Very fun. I find this form of mutant most enjoyable when the circled cells are not given, and this was great for playing with these constraints to a solution.

Thanks for the nice creation.

Re: Nice puzzle ...
Glad you enjoyed it.

I don't believe I've ever written an arrow sudoku with either a given number on an arrow or inside a circle. I'm not sure why you would do that since it diminishes the novelty of the variation, but other authors follow their own rules.
