Referee pours out a bunch of stuff. The contestant has to count how many there are. Scoring is based on exactness.
Hmm that might be hard.
Contestants run through a forest counting varying things. Trees, or whatever.
The contestant gets a giant, symmetric block of cheese, and a knife. They should cut the cheese in two and place the halves on two stands. Whoever cuts it most evenly, wins.
Given a bunch of homogenous mass, like sand, weigh out a given amount. Or, weigh out two amounts (at least 1 lb). Whoever is closest is the winner.
