Factoid: The slot machine was invented in 1895 by Chares Fey in San Francisco.

Sep 18, 2018 Progressive Slots: The progressive slots take a certain percentage of the money played and add it to a pool for the top jackpot. First and foremost, It is never wise to play a progressive machine with less than the maximum coins - stories abound of people losing out on lesser progressive jackpots because of short coin play. Certain states in the US require the pay-outs to be in a certain range (typically above 80%), and this can be discovered with a bit of trawling through your state’s gambling laws. For example in Nevada, the gaming board states that the machines must have a RTP of 73% while in Mississippi, it is 80%.

It is not accidental that two-thirds of every casino is littered with row-upon-row of slot machines of every type imaginable. The reason is that they provide the most profit to a casino ..and billions of dollars in tax revenue to the state. (The state of Nevada collects a $250 annual tax plus a $20 quarterly license fee per slot machine plus a percentage - about 5% - of gaming revenue.)

Slots account for more revenue to a casino than all other gambling games combined. Their formula for success is simple. They make money by paying out less than they take in. They are popular because players don't need any gambling knowledge and slots require only a very small bet. There are more than 200,000 slot machines in Las Vegas.

Most slot machines work the same way. The player pulls a handle or presses a button to spin a series of reels (typically three) that have pictures printed on them. You win when certain combinations of pictures line up with a pay line in the middle of a viewing window. The payout depends on which pictures land along the pay line. Some machines have multiple pay lines. A pay table (chart) tells you the amount of the payout. It is usually found on the front of the machine, above or below the area containing the wheels. While you can lose your money faster, the payout percentages are always better if you bet the maximum amount of coins on each “pull.”

All slot machines in use today in casinos are electronic (computerized) rather than mechanical. As a general rule, reels, handles, sound effects and other attributes are there to make them appear to be like older, more familiar, mechanical machines.Themed slot machines that require the manufacturer to pay a license fee (such as one named after a movie star, cartoon character, TV show, etc.) generally have lower payouts since the additional cost must be recouped. So stick with the traditional machines (such as the Double Diamond, Blazing 7s, and Red, White and Blue) that pay back more.

As a general rule, slot managers place their most popular - and best paying - machines in areas that generate excitement - such as near the front entrance and other high traffic areas. Some popular slots - such as nickel machines - are placed in the rear of the casino to get people to walk to the back. High payback machines are also sprinkled throught the casino floor.

Be aware that the higher the cost per 'handle pull,' the higher the payout. According to one industry insider, the so-called 'hold percentage' on the Las Vegas Strip averages 11% for nickels (that is, 89% is paid back), 6.5% for quarters, 4.5% for dollars, and 3.5% for five dollars and above. (The Nevada Gaming Control Board has a slighty different figure. See below.)

The payback percentage for Las Vegas (and all Nevada) slot machines are a known factor. Because they are taxed, all machines are strictly controlled and keep track of 'coin in' and 'coin out' which, overall, is a matter of public record. Manufacturers program each machine to payback a specific percentage which is based on a span of ten million handle pulls! Any slot can (and does) pay out more or less over a shorter period. It might pay out 400% today ..or 20% for a week.

A good website on slot machine gambling is located here .. and they have no advertising whatsoever.

The newest wrinkle in slot machines is coinless slots. They use bar-coded paper tickets instead of coins and are known as “ticket in/ticket out” ('TITO') machines. The traveling coin gal (and coin cups) are fast becoming a thing of the past. You feed bills and get paid in vouchers which are redeemed at the cashier’s cage. Don't forget to redeem the tickets! Some have expiration dates on them.

Video poker

Although poker machines have been around since 1964, video poker did not become popular until 1979 when International Game Technology (IGT) introduced its electronic “Draw Poker” machine. Video poker adds the element of skill and players are given decision-making options that regular slots don’t offer.

Video poker slots work the same way as regular rotating wheel machines. Instead of a reel, they have changing playing card images. They are generally based on five-card draw poker.

A series of five cards are generated from a freshly shuffled 52 card deck for each play and shown on the screen. The player discards some (or all of the cards) and replacements for the remaining cards are drawn. While you are deciding which cards you want to hold, the remaining 47 cards are constantly shuffling. After you decide and hit the button again, the cards stop shuffling and the x-number of cards you need to fill your draw hand come off the top and occupy the vacated positions.The objective is to get the best poker hand. Again a chart indicates the amount of the payout.

The most basic version pays on two jacks or better, but there are variations, such as “wild” cards.

All video poker is not alike. Be certain you are playing a “full pay” game which pays out 99.5% of incoming coin. They are known as a “9/6 JoB” machines – which stand for a payout of 9 coins for a full house and 6 coins for a flush with one coin inserted. (JoB stands for “Jacks or Better.”) The paytable for a full-pay or 9/6 JoB machine looks like this:

Royal Flush 250	Straight Flush 50	Four of a Kind 25
Full House 9	Flush 6	Straight 4
Three of a Kind 3	Two Pair 2	Jacks or Better 1

A casino can tighten a Jacks-or-better video poker machine by simply paying out less for a full house and flush. The most common way that a casino increases it's win is to pay only 8 for the Full House and 5 for the Flush. This is a short-pay 8/5 machine. The casino keeps an extra 2.2% on these machines.

A “10/7 DB” video poker machine (Full House=10 coins, Flush=7 coins) is better yet Payout (when played perfectly and max-credits) is 100.1%. Double Bonus Poker (DB) is a variation on video poker in which the payout for two pair is reduced from two to one in exchange for greatly increased payouts for other hands ..like a payout of 4000 for a Royal Flush.

The best place to play video poker is downtown or at such off-strip properties as Sam’s Town. A great video poker website is VideoPokerReview.com.

A couple of playing hints: Never keep a high card kicker with a pair; draw three cards. Hint No. 2: Always go for the Royal Flush if you have four of the five needed ..even if it means giving up a high pair. The odds are one in 52 that you will hit the needed card ..and Royal Flushes pay up to 4,000 to one if you put in the maximum number of coins.

Slot machines and the law

All slot and video poker machine models are tested by the state of Nevada to be certain that all results are based on a random number generator (RNG.) A new machine can’t be introduced until it meets all state regulations and technical standards. Because gross revenue is taxed, every machine keeps track of the money paid in and the winnings paid out.

Winning at slot machines is pure luck. And there is no such thing as a machine being “ready to hit.” The chances of winning never change whether it is the first or one hundredth pull. And a machine that hasn't paid recently is not due to win.

While winning combinations are determined on a totally random basis, the overall payback percentage is set on a standard machine. A casino tells the slot machine manufacturer what percentages it wants specific machines to pay back and that amount is programmed in. So, some machines
