Any straight line of three connected cells on the grid (vertically, horizontally or diagonally) firstly cannot contain only the same digit (e.g. 2,2,2) and secondly cannot contain three different digits (e.g. 3,1,2)

On the green line adjacent digits must be two or more apart.

The green square shows a digit which is lower than its orthogonal neighbours
