Blockchain 3D and VR Explorer
This is a tool to help people understand blockchains by providing interactive visualisations in 3D and VR. This is not a game but an educational and exploratory tool available for free and not-for-profit on iOS, Windows, Linux, MacOS and Android.
The tool supports the Bitcoin network at present, and lets you enter a starting address or transaction, then navigate the network as far as you like (or as your hardware will allow) to see inflows and outflows, all in glorious 3D (or VR with Google Cardboard).
It is available free from This project will become open source sometime Q1 2018.
