100 Door Codes Bonus 3 Walkthrough:
1. Look at the clue above the door which says "B down down = 1".
B down down = 1 because if you start at B, and move down 2 times, you draw the number "1".
Figure out the other three numbers:
(D = down, U = up, R = right, L = left)
B(DD) = 1
A(DR), A(RDD) = 9
B(LDRDL) = 5
A(DRDLU), A(RD) = 8
DOOR CODE: 1958
2. Proceed to the next 100 Door Codes level!
