I’ve been playing around with this recently and it’s super interesting.
The challenge with on-chain based blockchain games is that they become complete information games by definition. Like Chess, you can look at the board and see your opponent’s pieces at any time.
Brian and the team have created a sci-fi inspired space exploration game that uses zkSNARKS to create a blockchain based “fog of war” (think Starcraft on Ethereum), where you never know your enemies movements until it’s sometimes too late. Inspired by the novel of its namesake.
It’s a very early demo, running on the Ropsten testnet, but if you’re into this sort of thing, take a look!
