The nature of carnival games

Quote:

BOTTLE TOSS

Six bottles are stacked in a pyramid. In order to win this game, the victim
must knock all of the bottle down by throwing a ball at them.

This carnival game can be switched to be easy or hard to win. The key to this
game is that half of the bottles are made really heavy while the other half
is really light. When the base of the pyramid is made of the lighter bottles,
the game is easy to win. This is usually the way the game is set up when the
carny demonstrates that the game can be won. However, when the victim pays
money for a try at the prize, the heavier bottles are stacked on the bottom,
making the game nearly impossible to win
