Corn Holes

Summary
On day 4 Dad was suggested he should check the packs of Cornhole games.

Facts
On the back of 2 of the packs there was a maze and a word search. On the back of the third a piece of tape was covering the maze with the code XXXXO on it.

Theories

 * 1) The maze could lead to the combination for the directional lock on the Comics Chest. Once solved the combination could be:
 * 2) Down, Down, Down, Down, Left, Up, Left, Down, Down, Right, Down, Down, Right, Down, Left, Down, Right, Right, Down. Using the whole maze, not excluding the duplicates caused by going in a single direction multiple times.
 * 3) Down, Left, Up, Left, Down, Right, Down, Right, Down, Left, Down, Right, Down. Using the whole maze solution, excluding the duplicates caused by going in a single direction multiple times..
 * 4) Down, Down, Down, Down. Using XXXXO code on the back as a hint to only use every fifth direction, but not excluding the duplicates caused by going in a single direction multiple times. Tried on 12/7, did not work.
 * 5) Down, Left, Up, Left. Using the XXXXO code on the back as a hint to only use the first 4 directions in the maze solve, excluding the duplicates caused by going in a single direction multiple times.

Results
The XXXX0 was a clue to use the last digit of the zip code, which helped open the comic book chest.
