Stay on the bull as long as you can. A prompt pops up next to the bull: an arrow, or a round A or B button (A is the inner button, B the outer one, as on the Arduboy). Press it before it runs out and the bull bucks. Points for every hit: the faster you press, the more you get. The wrong button or too slow is a strike (top left); three strikes and you're bucked off. Every 7 seconds without a strike is a +250 bonus, and eight hits in a row wipes a strike. It gets faster the longer you ride. After a ride, right rides again and left goes to the title. Tap the screen once if you don't hear the music.
