This is a new idea for a sudoku variant puzzle adapted from standard Arrow Sudoku. Please give it a try and let me know what you think. In normal arrow sudoku the number in the circle is equal to the sum of the digits along the arrow. In this variation, each circle has two arrows and you take the difference of the two sums.

Difference Arrows

Each row column and 3x3 box must contain the digits 1-9.
Each circle has two attached arrows. The value in the circle is the sum of all the digits along one of the attached arrows minus the sum of all the digits along the other attached arrow.

Play some of my sudoku variant puzzles here. I have had a passing interest in sudoku and killer sudoku puzzles for some time. During the Coronavirus lockdown I discovered the Cracking The Cryptic YouTube channel. This opened up to me a whole new world of sudoku variant puzzle types that I had been completely unaware of.

This puzzle was made for the November 2020 monthly puzzle prompt in the CtC fan discord server which was on the theme of modern art.

Arrow Sandwich Sudoku

This puzzle combines sandwich sudoku and arrow sudoku. I am quite pleased with the symmetrical arrangement and aesthetics of the clue placements and given digits. The broken arrow idea is quite fun too I think.

Fairy Chess Sandwich Sudoku

This puzzle was originally intended for the May 2021 monthly puzzle prompt in the CtC fan discord server. However, I didn't get it finished in time so I found a way to fit the theme of the June puzzle prompt instead.

More Difference Arrows

This is another puzzle using difference arrows. This one has no given digits to start you off but shouldn't be too much harder. Please give it a try and let me know what you think.
