Hi there,

I uploaded this sudoku to SudokuPad but unfortunately the rules where not included. So I don’t remember the rules to solve it.

The X = sum to 10 of neighbouring cells and V (same for 5 as sum) I am sure about but the circles I don’t get. First I thought its each one number from 1-6, but that doesn’t work. Now I tried with uneven numbers but got stuck here and feel like this also could be the wrong rule.

Anybody knows this one or has another idea?

Here now with the circle logic that the number shows the amount the circle has the number in it:

I am not sure how to continue from here, any tips what I am maybe missing?

Cage in c6 is 27, in c8 is 13 and in c9 is 8.

thanks for the help!

Rules:

Normal sudoku rules apply, and all clues are standard.

Cages: the sum of the digits inside each cage is equal to the small number in the top left corner.

Renban lines: purple lines contain a non-repeating set of consecutive digits in any order.

Does anybody has a tip what to consider or focus on to solve the rest?

"Combined Effort"

By James Sinclair

Rules:

Normal sudoku rules apply.

Arrows: the sum of the digits along an arrow is equal to the digit in the connected circle.

Double arrows: the sum of the digits along the burgundy line is equal to the sum of the digits in the circles at each end.

Digits in cells separated by a black dot have a 1:2 ratio.

I am now stuck how to proceed. What logic would help me to solve? I’m still struggling with wings, if that is a way to go forward.
