I’m trying to create an array that keeps track of which lines are already hit so they aren’t checked repeatedly if I allow the game to continue until another bingo is hit. This is where my problem is occurring. winningLines is defined outside the function so it’s a global variable. I create a new key containing the ID of the bingo card and attached an associative array to it. It then exists until the $.each(bingoLines function occurs. Then it stops working. The console.log lines shows where it works and where it dies.
