All the rules and strategies of Sudoku "search to nine" apply: diagonal distances must be projected to an horizontal line, and can point to any nine in that diagonal. (Like in this puzzle)
Rephrasing those rules; if there is a 1 on an arrow, the cell immediately adiacent must be a 9. If there is a 2 on an arrow, the second closest cell must be a 9 ... Etc.
In addition, there is a non-consecutive constraint, so no cells containing consecutive numbers (difference of 1) can share a border in the whole puzzle, just corners are allowed.
The puzzle is way simpler than it looks and does not require bifurcation. Solve online link by Jade_pv here (no check); https://f-puzzles.com/?id=ydwon8tb
Lösungscode: 1st row, then last row
