Wheel of Fortune (U.S. game show)

A contestant spins the wheel to determine a dollar value and guess a consonant. Calling a correct letter earns the value before the corresponding flipper, multiplied by the number of times that the letter appears in the puzzle. Calling a correct letter keeps the wheel in the contestant's control, allowing the contestant to spin again, buy a vowel for a flat rate of $250, or attempt to solve the puzzle. Contestants may continue to buy vowels so long as they have enough money to keep doing so, until all of the vowels in the puzzle have been revealed. Control passes to the next contestant clockwise if the wheel lands on Lose a Turn or Bankrupt, if the contestant calls a letter that is not in the puzzle, calls a letter that has already been called in that round, fails to call a letter within five seconds of the wheel stopping, or attempts unsuccessfully to solve the puzzle. The only exception is the Free Play wedge, on which the contestant may call a consonant for $500 per occurrence, call a free vowel, or solve the puzzle, with no penalty for an incorrect letter or answer.
