50. Picross E
It's kind of an odd choice, to be honest, especially as their are other games I enjoy more that I've left off the list. But I wanted to include this one based my love for Picross as a whole. I started with Pokemon Picross since that was free-to-play for the 3DS. After enjoying that game so much, I hunted down all the other Picross games I could get my hands on and fortunately Jupiter has put out a new one or two every single year for the past decade so I've yet to run out of puzzles. Drinking a cup of tea and listening to a podcast or youtube video while solving puzzles has become my go-to relaxation when I'm stressed.
