hi,dears. The avg. payouts of vegas's slot is about 90%.What is it means? I search the google,some one said it is in a long run for example 1 week.some one said the "long run" is one year. And the most important is about 90%'s calculate method. if a long run means 1 week. a.100 customers put 100,000 cash in the slot to play.Whatever they paly,and casino get the 10,000 in a week. b.100 customers put 100,000 cash in the slot.Spin and Spin,in the end, casino get almost all the 100,000 cash.Because the reward(win back) is plus to the basic calculate.(100,000 cash+9,900,000 reward)*10%=100,000 Do you think which is right? and how long is the "long run".
