Description:
    Initially I implemented the algo in Python, next snippet shows the algo:
        def check(x:int, y:int) -> bool:
            m = 6
            a = (x  + 3) % m == y % m
            b = (33 - x) % m == y % m
            return a or b
    After that I just ported it to asm, see comments in source file
