Hello @tempestinyang

Steem Bingo is a game promoted by @xpilar. It's based on the classic bingo we all know, where prizes are awarded for collecting columns, rows, and a full card.

Once you have a bingo card, you should check the round you're playing; just visit the website.

Then, just wait for the automated draw for that round to take place. The prizes are distributed automatically.

I hope this clarifies your doubts.
