Do we have to win all games or play all games?

I have a list of games that would be good for speedrunning that are not up. How do I make a game on the website?

I recently saw that there are only 3 verifiers, and the most recent run was 1 month ago (not sure if people dont run the game) but I would like to help!

I have been trying ssg runs, and keep getting to the end but failing. Please send tips.
