Baby Bingo by Maurice Janssen

Baby Bingo is unlike traditional bingo where someone calls out letters, followed by numbers until someone yells BINGO! In Baby Bingo no letters are required and only one number is needed to get a bingo. A random participant thinks of any number from one to thirty. If they see their number on a card, that's a bingo and places it face-down. Cards that do not have their number, they put aside (in their pocket or purse). The performer looks away while they look through the cards.

The participant is directed to a prediction that coincides with how many bingo cards would have their lucky number. The performer (with zero questions asked) knows they are thinking of a two-digit number and whether it's odd or even.

Next, a numbered word list is shown to the volunteer. They find their number and remember the word next to it. You redirect the attention to the face-down bingo cards and reveal one picture has something to do with the word they are merely thinking of and proceed to reveal their exact word.
