That expected value is known in the industry as RTP - return to player - and is generally in the 85-98% range. Once a game is certified as having that RTP, it can't change - BUT the standard deviation can vary wildly from machine to machine, with some paying out little and often, and others having a more 'lumpy' distribution of not paying out much and then paying out large prizes every so often. High rollers will often go for these lumpier machines, staking large amounts and hoping for the elusive x1000 multipliers.
- joezydeco 12y agoVery good point. But players should also know that a given machine can be released in multiple payout levels. You can have a row of identical games but the game in the middle could be set at 95% and the others around it set to 87%. And the casino doesn't have to identify which is which. Sometimes you can glean this from the payout tables, you can almost always glean it from video poker games. There's a voodoo science around how casinos are laid out and how games are arranged to maximize cashflow. You can get a degree in this at UNLV.
- lewispollard 12y agoI don't know about the US - but here in the UK all machines are required to clearly display the return to player value in the terms of the gambling license.
- joezydeco 12y agoYeah, sorry about the US-centric answer. Having payouts labelled is a very nice thing. Obviously Las Vegas was built on the players not knowing or understanding their long-term odds.
