I'm curious what you really want to do. You can make a provably fair version as a game of chance, essentially using random numbers from hashes of both players fighting for the hill. Of course, then whoever controls the hill only has a 50% chance of retaining control unless you introduce other factors like, shields, power ups, longevity, hit points, or superhero powers, jedi force, etc.
Then it becomes a sort of RPG or Diablo clone. You'll need 3D graphics. I'm sure the bitcoiners here have awesome graphics cards. I'm pretty sure the litecoiners have really awesome graphic cards.
It's hard to explain - it's an endless game where the current person can be pushed off the hill by someone smarter or more clever.
We play this in IRL and it's fun trying to outdo each other.
I love how smart people's brains work - and this is kind of an exercise for us.
