/*
    Every bit represent a side/corner: 1 same tile, 0 different tile:

    0 1 2
    3 x 4 -> 0b7654_3210
    5 6 7

    So single tile surrounded by different tiles would be:
    0 0 0
    0 x 0 -> 0b0000_0000
    0 0 0

    A top left corner tile would be:
    1 1 0
    1 x 0 -> 0b1101_0000
    0 0 0
