发明名称 Gaming machine with high volatility index
摘要 A gaming machine comprises a spinning reel display showing a plurality of symbols on each of a plurality of rotatable reels. The reels are rotated and stopped to place the symbols of each reel in visual association with a pay line. A winning combination of displayed symbols triggers a payoff. The distribution of payoff values and probabilities results in a high volatility index, so that the distribution is similar to a state-run lottery.
