Drag the cards you want onto the grid. You need at least 1 from each category.
Remove a card from the grid by simply dropping it outside the grid.
Press start to lock in your choices, click a card to cross it off!
The time when you started will be shown for screen-shotting and verifying. No cheating now!
Shout "bingo!" super loudly over VoIP when you get a row or column. Alternatively, save "bingo!"s for when the session ends to give all cards a chance.
