Slot machines are popular casino games that constitute about 70% of the average casino’s income. The player pulls a handle to rotate a series of reels that have pictures printed on them. Winning or losing is determined by which pictures line up with the pay line, a line in the middle of a viewing window. Some believe skill is involved in the game, but the probability of a win is determined by the game’s random number generator. Who invented the slot machine? Discuss
