10000 possibilities
Something different this time! No keys!! I bought some combination padlocks with 4 digits, and it seemed like a good idea to fiddle each other with the combination known only to the other person. So we start by changing the combination on the padlocks, hiding it from each other, then locking each other in the fiddle with the padlock on top. We now had to guess the combination, in a race to see who gets out first!
The problem was that I did not anticipate it would take so long to go through 10000 combinations! We were in this for a long time. And to make matters worse, I actually forgot what combination I set on Anahi’s fiddle! True story :) Don’t worry, we got out eventually, although it took the better part of the afternoon. Why are we both so stubborn, we just don’t want to give up the combination, we both want to win!!
