A fully on-chain checkers game. Built on Sui by Ethos.

Ethos Checkers consists of a smart contract that allows the player to mint a game that is playable on chain.

You can't yet play Ethos Checkers, but you can play Ethos Chess and Sui 8192. We are working on a front-end that will allow you to play Ethos Checkers soon.

This project is built on the Sui blockchain, which provides the performance necessary for a great game experience. Every move is a transaction that is recorded on-chain, making the gameplay verifiable, shareable, and transferable. Each game is an NFT that can be sent to anyone and will display in a web3 wallet (such as the Ethos Wallet).

This project uses the Ethos APIs to make the Ethos Checkers game accessible to people who do not yet have a web3 wallet. It allows them to start playing the game right away without having to figure out a wallet first.

As far as the game is concerned every player has a wallet because the Ethos APIs provide a unified interface for both players with and without wallets.

The primary methods that this game uses to do this are:

<EthosWrapper>, SignInButton, and ethos.transact()

Each of these can be found by searching in js/game.js

• The Ethos APIs currently require react and react-dom which is why they are included.

The Ethos Checkers smart contract is written Sui Move for deployment on the Sui blockchain. It consists of three parts:

1. Game: Primarily entry functions for making moves and recording the overall game state.

2. Game Board: Most of the game logic.

The code for the smart contract is in the "move" folder.
