I'd been looking for a codebreaker game recently so cypher lock was fun to play for me! https://minigames.world/en/feed/cipher-lock

I think so. In the same way their source material is fun I guess

You found these fun? As I can't imagine finding them fun. Can I ask, how long did you play? How often would you see yourself returning to this site?

I still have Quantum Forge open in a tab. I think that probably says more about me than the game though?

Which are the fun games? Any suggestions?

What source material are you talking about?
