Android App for the 2 player board game Abalone (Abalone wiki)
Screenshots below.
Quick inspiration backstory:
My friends and I found an abandonded box of the actual board game in our college dorm. We learnt the game from the instrucions in the box and played quite a bit.
The game seemed to work similar mental muscles as chess.
I saw an (and still think there is) an opporuntiy to build a online multiplayer community around this game.
I have never heard of the game before or after that (disclaimer: I haven't even read the wiki link I just added for context).
