Three spectators are handed some cards with numbers on them. Each calls out a number from his set (free choice) creating a three-digit number (free choice). This is repeated until you have three different, three-digit, numbers. All the numbers are added and the total matches the prediction, which could have been emailed to them in advance.
Comes with nine specially printed jumbo cards and an instructional booklet. Can be repeated 198 times with different outcomes. Self working.
