Setting up
Pick number bingo or a word set, the pattern and how fast to call. The TV shows the code and a QR code while people join.
How live bingo works
One screen for the calls, one phone per player, and a host who can play along too.
Playing
The TV shows each call and a board of everything called. Phones show each player's card. When a card has the pattern, the player taps BINGO and the game checks it.
After a bingo
The host sees the winning card to read out, then keeps going for more winners or ends the game.
Call the first number tonight
Open it on the TV, share the code, and every phone has a card in seconds.
