There is a panel with 14 boxes. Inside each box is a hidden prize
Every person in the audience has one number, then you do a raffle and the person with the winning number has a choice to Pick a Box.
The compere will then try and buy the box from the contestant.

You take 14 numbers in the raffle. Each player come to the stage and one-at-a-time you ask them three simple general knowledge questions. If they get them right, they get to pick a box.
However, the host would try to buy back the keys, offering different prizes.

Behind the boxes you can type text, or place a picture of your prize.
