Probability Of Slot Machine Jackpot

Founded in 2011, Probability Games can't quite be classed as a brand spanking new name in the industry. Although, having said that, the software company is far from making any huge splashes in the online and mobile slot machine industry, remaining relatively unknown to the vast majority of punters on the web. In a typical weighted slot machine, the top jackpot stop (the one with the highest-paying jackpot image) for each reel corresponds to only one virtual stop. This means that the chance of hitting the jackpot image on one reel is 1 in 64.

In a modern slot machine, the odds of hitting a particular symbol or combination of symbols depends on how the virtual reel is set up. As we saw in the last section, each stop on the actual reel may correspond to more than one stop on the virtual reel. Simply put, the odds of hitting a particular image on the actual reel depend on how many virtual stops correspond to the actual stop.

In a typical weighted slot machine, the top jackpot stop (the one with the highest-paying jackpot image) for each reel corresponds to only one virtual stop. This means that the chance of hitting the jackpot image on one reel is 1 in 64. If all of the reels are set up the same way, the chances of hitting the jackpot image on all three reels is 1 in 64³, or 262,144. For machines with a bigger jackpot, the virtual reel may have many more stops. This decreases the odds of winning that jackpot considerably.

The losing blank stops above and below the jackpot image may correspond to more virtual stops than other images. Consequently, a player is most likely to hit the blank stops right next to the winning stop. This creates the impression that they 'just missed' the jackpot, which encourages them to keep gambling, even though the proximity of the actual stops is inconsequential.

A machine's program is carefully designed and tested to achieve a certain payback percentage. The payback percentage is the percentage of the money that is put in that is eventually paid out to the player. With a payback percentage of 90, for example, the casino would take about 10 percent of all money put into the slot machine and give away the other 90 percent. With any payback percentage under a 100 (and they're all under 100), the casino wins over time.

In most gambling jurisdictions, the law requires that payback percentages be above a certain level (usually somewhere around 75 percent). The payback percentage in most casino machines is much higher than the minimum -- often in the 90- to 97-percent range. Casinos don't want their machines to be a lot tighter than their competitors' machines or the players will take their business elsewhere.

The odds for a particular slot machine are built into the program on the machine's computer chip. In most cases, the casino cannot change the odds on a machine without replacing this chip. Despite popular opinion, there is no way for the casino to instantly 'tighten up' a machine.

Machines don't loosen up on their own either. That is, they aren't more likely to pay the longer you play. Since the computer always pulls up new random numbers, you have exactly the same chance of hitting the jackpot every single time you pull the handle. The idea that a machine can be 'ready to pay' is all in the player's head, at least in the standard system.

When you hit the slot machines in a casino, you'll have dozens of gaming options. Machines come with varying numbers of reels, for example, and many have multiple pay lines.

Most machines with multiple pay lines let players choose how many lines to play. For the minimum bet, only the single line running straight across the reels counts. If the player puts more money in, he or she can play the additional horizontal lines above and below the main pay line or the diagonal lines running across the reels.

For machines with multiple bet options, whether they have multiple pay lines or not, players will usually be eligible for the maximum jackpot only when they make the maximum bet. For this reason, gambling experts suggest that players always bet the maximum.

There are several different payout schemes in modern slot machines. A standard flat top or straight slot machine has a set payout amount that never changes. The jackpot payout in a progressive machine, on the other hand, steadily increases as players put more money into it, until somebody wins it all and the jackpot is reset to a starting value. In one common progressive setup, multiple machines are linked together in one computer system. The money put into each machine contributes to the central jackpot. In some giant progressive games, machines are linked up from different casinos all across a city or even a state.

Some slot-machine variations are simply aesthetic. Video slots operate the same way as regular machines, but they have a video image rather than actual rotating reels. When these games first came out, players were very distrustful of them; without the spinning reels, it seemed like the games were rigged. Even though the reels and handles in modern machines are completely irrelevant to the outcome of the game, manufacturers usually include them just to give players the illusion of control.

These are only a few of today's popular slot variations. Game manufacturers continue to develop new sorts of machines with interesting twists on the classic game. A lot of these variations are built around particular themes. There are now slot games based on television shows, poker, craps and horse racing, just to name a few.

What Is a Progressive Slot, and How Does It Work?

On most slot machines, the jackpot is a fixed amount, but on a progressive game, the jackpot rises as players put coins in the machine and spin the wheels. A tiny percentage of each coin played is used to “feed” the jackpot. There are three types of progressive slot machine games.

Standalone Progressives

A standalone progressive slot machine has a jackpot ticker on the game, but only bets placed on that specific machine feed the jackpot. This was, at one time, the only kind of progressive slot machine game available, but most progressives feature multiple machines that are linked together. Still, so many standalone machines were manufactured that these games are still easily found in casinos throughout the world. Usually the jackpot on the games will be under $10,000.

Local Progressives

Local progressives were the next step in the evolution of this type of game, and they’re still commonly found. These games feature jackpots within a specific casino that are linked. This network can include as few as a dozen or so machines, or it can include a hundred machines—it just depends on the casino. Usually the jackpots available on these games are under $1,000,000, and often they’re under $100,000.

Wide Area Network Progressives

These are some of the most popular casino games on the market today. A wide area network jackpot links slot machines from multiple casinos in the same state. This allows the jackpot to accumulate into astronomical sums of money, often over $1 million and sometimes even over $10 million. The most well-known brand of wide area network progressives are the Megabucks games from IGT, which is the most successful slot machine design company in the world.

How Do You Win a Progressive Jackpot?

No strategy or system can increase your chances of winning a progressive jackpot on a slot machine game. The odds of winning are similar to the odds of winning the lottery, although you get many more chances of winning per hour with a slot machine game than you would get playing a lottery game.

An important thing to keep in mind about progressive jackpots is that they don’t become “due”. The chances of winning are astronomically small no matter how large the jackpot has gotten. It’s possible for a jackpot to grow large enough that a bet on a particular slots game will be a positive expectation bet, but it’s not a practical opportunity to win. A 1 in a million shot is still a 1 in a million shot, even if the jackpot is up to $2 million.

Online Progressive Jackpots

With the rise of online casinos, progressive jackpots on the Internet have become just as popular as the games in actual land-based casinos. Microgaming is one Internet casino provider which has established its fame and reputation based largely on its large assortment of fun, colorful, and relatively loose progressive jackpot games.

Huge Slot Machine Jackpots

Online progressives work just like their land-based cousins. Every wager you make on your computer feeds a tiny amount into the progressive jackpot for that game. Since lots of players are now gambling from the comfort of their homes, these jackpots can become just as large and life-changing as the progressives in Vegas or Atlantic City.

Most Popular Progressive Games

Megabucks is one of the most popular progressive networks available. The probability of winning this jackpot has been estimated at 1 in 50 million. The amounts won on this machine vary from $10 million into the hundreds of millions. Like many lottery games, Megabucks is paid out as an annuity over 25 years.

Wheel of Fortune is a popular brand of slot machine, and it’s available in multiple denominations. One of the most common versions is the quarter version, which has a starting jackpot of $200,000. The jackpot on this game has gotten close to $2 million in the past, but it’s usually won when it’s still under $1 million.

The dollar version of Wheel of Fortune progressives starts with a $1 million jackpot. It’s not unusual for the game to reach $5 million or more, and it’s almost reach $10 million on occasion. Like Megabucks, this jackpot is paid out as an annuity over time.

Elvis isn’t just the king of rock and roll. He’s also a symbol of classic Vegas, so it’s entirely appropriate that he has a progressive slot machine network named after him. The game starts with a $100,000 jackpot, and it costs 25 cents per spin. Keep in mind that to be eligible for the jackpot, you have to make the max bet, which is 3 coins, or 75 cents. We don’t recommend playing progressive slots without making the max bet, because you usually won’t be eligible for the top prize unless you do.
