Cryptle is Wordle for the Web3 World. Players compete to guess their (randomly selected) words (that are different for each player). Players that guess their word in fewer guesses receive payouts for their performance. In essence, users can bet on their own Wordle game outcomes.
Cryptle is our submission for the Chainlink Spring Hackthon 2022. Check it out here!

Cryptle was inspired by the desire to build a simple, easy-to-use, Web3 game that did away with complex and inaccessible tokenomics/strategies/learning curves in favour of enjoyable and accessible gameplay that benefits from the settlements layer of Web3.
We built Cryptle using Solidity, powered for the python-based Brownie framework for automation and testing. We used React to build the frontend and the web3.js library to interact with the smart contract.
We faced a few interesting design challenges around random numbers, and hiding sensitive information on the blockchain. See the video for more details!
Navigate to http://cryptle.xyz or https://geckods.github.io/cryptle/ to try it out. Note that at the moment, we are only live on the Avalanche Fuji test chain. Coming to other blockchains soon!
We have plans for a mainnet launch, more features, more optimizations, and more play-to-earn massively multiplayer online Web3 games!
