*** TODAY'S PUZZLE ***
A debut on the channel tonight for the constructor NEWS in a phenomenal collaboration with sujoyku called Arrow Dynamics. This is a very clever puzzle that has one or two eureka moments during the solve. Really enjoyable fare :)
Play the puzzle at the links below:
https://sudokupad.app/or42ce5os1
Rules:
Normal sudoku rules apply. Digits along an arrow sum to the digit in that arrow's circle. Each turquoise line is an Index Line, i.e. the digit in the Nth cell along such a line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.
