Although really simple to play (click on a cow and say how much you want to bet), this is a pretty deep game: Initially you'll be able to perform just a few of 30 possible cow-tipping techniques. As you witness others tipping cows, you'll learn "facets" of those techniques. When you know at least 5 facets of a technique, you'll be able to perform it yourself, and teach it to others.
With higher bets, there's a greater chance of performing more exotic techniques including pile drivers, complex flips and backward falls.
