A colleague of mine is looking for a card game he heard about that requires students to use four numbers to calculate a total of 1 to 24. Apparently there are dice involved somehow, he thinks possibly to determine the target number. The person who told my colleague about the game said that because the target number can be anything from 1 to 24, thus making it more challenging.
If anyone out there knows what game he's looking for, please e-mail me. Thanks.
