Great opportunity to share an older project:

https://www.AssemblyArena.com - an educational game for people who would like to learn and/or program in assembly.

It's a (non mobile-optimized) web-based PvP assembly programming game. The syntax is highly inspired by x86 assembly and the game itself by Core War. There is also a small tutorial and a ranked ladder powered by Glicko-2.
