Reverse engineered prompt

Build me a bingo tracker web app where I can register multiple 5x5 bingo cards with unique IDs, and the center space is always free and marked automatically.

I want to be able to start a game, enter drawn numbers manually, and have the app mark every matching spot on every card. It should support two winning modes, one for a completed row or column, and one for a full card. Please show clear alerts when someone wins or when a card is just one number away. Also make sure it blocks bad inputs like duplicate numbers, numbers outside 0 to 99, duplicate card IDs, and trying to draw when no game is active.

I’d like the game state to stay saved in the browser so a refresh doesn’t lose anything, and I want an undo button plus a safe two step finish action so I don’t end a round by mistake. Use a clean simple UI and look up current docs online if you need to.

Are you gonna build this?
