Last year, I had my students play 4 corners. It was actually suggested by a
student, not knowing that the outcome was exactly what I wanted.

Here is how it works, have the students randomly go to any corner of the
room, and then have the calculator pick a random integer between 1 and 4.
Those people are eliminated. Then have the students again randomly pick a
corner, and then again pick a corner to eliminate. Keep track of the number
of students at each round, and graph the data when there is only one person
standing. (If there are two people left, I don't let both get eliminated,
because the transformation using the logarithm wouldn't work)

I works fairly nice, the data shows an exponential decay, and the students
remember playing from elementary school, so hey think it is fun.

Hope it helps!
