Hello, I’ve started a new ruby quiz for secure (crypto) contract blockchain scripting. Challenge #1 - Create a 3x3 Tic-Tac-Toe Player vs Player Game Contract. Let’s use the “Creating a Tic-Tac-Toe Smart Contract” tutorial and “real-world” sample contract from the EOS.IO blockchain. The challenge: Code a contract for a 3x3 tic-tac-toe player vs player game using sruby :-). Can you do better? Post your code snippets (or questions or comments) on the “official” Ruby Quiz Channel, that is, the ruby-talk mailing list. Cheers. Prost.
