Randomly draw 4, 5 or 6 cards from a shuffled deck of cards. Using any of the four basic mathematical operators, combine all four cards to form a pre-defined number.
I've played this game with Mo, Charles Zhu, Charles Au, Josephine and Irfan, and this really provoked some thoughts in me with regards to problem solving.
- One has to simplify the problem into its essentials.
- There can be many solutions to one problem.
- With a defined criteria, the best solution can be found.

There are actually many variations of this game. There was something like this for Math Week '06:
Form teams/groups of people. From the randomly shuffled deck of cards, draw 4 cards and using any of the four basic math operators (repetitions allowed), form an equation which equates to 24 using all the 4 cards. The fastest group to come up with a valid solution wins.
Of course, there will be some combinations of cards which won't give 24, but 24 works for most cases.
