Parallel Parking
Every weekend, I drive into town for contactless curbside pickup at a local restaurant. Across the street from the restaurant are six parking spots, lined up in a row.
While I can parallel park, it’s definitely not my preference. No parallel parking is required when the rearmost of the six spots is available or when there are two consecutive open spots. If there is a random arrangement of cars currently occupying four of the six spots, what’s the probability that I will have to parallel park?

Rock-Paper-Scissor Puzzle
Start in any square and move one square at a time straight or diagonally. You can only move to a square that you can beat. Eg you can move from scissors to paper as scissors beats paper. Once you've been to a square, you can't return to that square. How can you visit each square?
