I made a game! It's tic tac toe with a twist. Every turn begins with one player selecting a square that will be up for auction. Each player then submits a blind bid.
The winner gets to put their letter down in that square. The loser loses their bid. After 3 in a row, you win!
All the code is here! All made with Phoenix/Liveview. https://github.com/cbh123/bidtactoe
