Playing with Our Expectations
"We’ve chosen a rule that some sequences of three numbers obey — and some do not. Your job is to guess what the rule is."
Revealing our Limitations
"Pick a number from 0 to 100, with that number representing your best guess of two-thirds of the average of all numbers chosen in the contest.
