For those looking for arcade games similar to Slope, but with more variety, I recommend checking out google doodle games It's a site with great free games, including arcade games that run right in your browser. There are no intrusive ads there, which is especially nice. The collection is constantly updated, so you can always find something new. Personally, I found some cool arcades there, which kept me at the screen for a long time. I advise you to try - there are really a lot of options, and all without registration.
