donbadabon: The location has been compromised with recent maintenance, and the container is missing. Guessing it was thrown in the woodchipper with all the cut branches.
So this one is being archived.
Thank you to all that attempted this one.
It wasn't very popular (7 finds in 8 years) but I enjoyed making it.
To solve this, notice that the boxes are grouped in pairs, with 6 columns each. For a total of 12 columns per pair.
Also notice there are 12 plinko lines.
Place the paired boxes above the plinko lines, and they tell you which column is moved where. For example the first column will move to the third column of the solution.
The first pair, when rearranged, will result in the number 52.
Repeat for the rest of the pairs and you will end up with 6 pairs of decimal numbers.
Convert those to ASCII and that is the solution.
