Since 1975, contestants have been spinning the wheel and risking bankruptcy to guess letters and complete the puzzle on the board. Contestants can buy a vowel and vie to be the first to solve the puzzle. The bonus round allows winners to add cars, trips, and up to $100,000 in cash to their winnings. Before Pat Sajak and Vanna White took the reins in the early 1980s, Chuck Woolery and Susan Stafford hosted the show. Dubbed "America's game," Wheel frequently goes on tour across the country and features celebrity and charity versions of the show as well.
