pinup-games-in.com is probably the simplest platform I’ve used in years. You only make a nickname and a basic password if you want your scores saved — that’s it. No email, no phone verification, nothing. I started using it because I was tired of endless sign-ups. The homepage already lists all available mini-games, so you can jump right in. They have logic games, timing games, visual puzzles, and more. It’s straightforward and very player-friendly.
