Tic-tac-toe game but it's actually called Zik-zak-zoo (& you can zk-verify you won thanks to RISC Zero)

Title is pretty self-explanatory, but let's dive into the details!

What is Zik-zak-zoo?

Zik-zak-zoo is a fun twist on the classic tic-tac-toe game, where:

• You play as 'Z' against the computer's 'K'
• The game logic is implemented in Rust
• You can prove your win using zero-knowledge proofs powered by RISC Zero

Quick Start

First, make sure rustup is installed. The rust-toolchain.toml file will be used by cargo to automatically install the correct version.

To build all methods and execute the method within the zkVM, run the following command:

RISC0_DEV_MODE=0 cargo run --release

How it works

1. The game uses a simple RNG for the computer's moves (LCR with MMIX parameters)
2. Your moves are recorded along with the initial seed
3. After the round is played, the game data is used to generate a zero-knowledge proof...
4. ... which get you bragging rights with cryptographic proof of your Zik-zak-zoo skills (well, if you won)!
