This is the third practice puzzle for the 2017 WSC.
Obviously some of the puzzles are going to come from the 6th round as it has new types. I figured I might as well start at the beginning of the round. This also seemed like a type that would suit my writing style.
The overall design idea was to make a long arrow and match the givens in the same place. I think it worked out well. The other 2 matching arrows just add a little bit extra to the aesthetics. This is probably the easiest puzzle out of the three practice puzzles so far. It's really a matter of making one single opening deduction and the rest of the puzzle flows pretty easily.
Rules for Sudoku
In this Sudoku, there are a number of arrows. Starting from the third digit on the arrow, each digit is the unit's digit of the sum of the previous two digits on the arrow.
