Normal sudoku rules apply.
Orthogonally adjacent cells can not sum to 5 or 10 without a green dot connecting them.
Cells connected by a green dot sum to 5 or 10.
All green dots are given.
Adjacent digits along green lines must differ by 5 or more.
Grey lines are just for visual purpose and do nothing.
