What Are The Odds Of Winning A Jackpot On A Slot Machine?

When you play any slot machine, it is safe to assume that you know you might not take home any big wins.

But, what are the chances of potentially winning a jackpot on a slot machine, and what triggers the jackpot on a slot? Better yet, can you tell if or when a slot machine is going to hit?

Continue reading this King Casino blog post to learn all there is to know about the odds of winning a jackpot, what happens if you hit the jackpot on a slot machine, and whether or not slot machine jackpots are random.

What Are The Chances Of Winning A Jackpot?

Before we can talk about the chances of potentially winning a jackpot, we’ll first discuss what a jackpot is. A jackpot is a rather large cash prize that can be offered in slots. It can usually come in two different forms: a progressive jackpot and a fixed jackpot. 

A progressive jackpot can increase any time a specific slot game is played and not won, while a fixed jackpot remains at the same price regardless of the number of people playing it.

Because jackpots are usually bigger prizes, the chances of winning them are generally lower than the regular prizes offered in slot machines. There is no set number for these odds, as slot machines can be influenced by a lot of things, such as the number of reels, symbols and win lines it has, the game’s Return to Player (RTP) rate, volatility and how big the jackpot prize is. 

However, the odds typically range between 50 million to one and up to 100 million to one. But it’s important to note that these odds may be higher or lower depending on the slot game and potential prize.

While those odds may seem astoundingly low, some players have won some impressive jackpot prizes playing slot games. For example, a Las Vegas winner bagged $14.3 million playing a Megabucks slot machine!

What Triggers The Jackpot On A Slot Machine?

Like any other win in a slot machine, a jackpot win is triggered by a Random Number Generator (RNG). RNG software determines the random outcomes on a slot, from spinning the reels to landing a winning combination.

So, if you spin the reels and land the jackpot, you have the RNG software to thank. The same goes if you do not land any matching combination; the RNG is still responsible for that too. 

Therefore, do not trust any cheat tips or tricks you may find online. Slot machines at licensed and regulated casinos cannot be manipulated to trigger a possible win; they do that randomly due to the RNG software. 

Can You Tell When A Slot Machine Is Going To Hit?

No, you cannot tell when a slot machine is about to hit. As mentioned above, slot machines are entirely random and cannot be predicted, so it is virtually impossible to tell when a game is about to hit.

However, some casino players may be superstitious people with unique playing beliefs. For example, some players believe that if you spin a slot machine long enough, it will eventually pay big. But, obviously, this is a myth. You could potentially hit the jackpot on your first spin, or you could play a million spins and win nothing. This is because, again, the RNG determines the random results.

Another popular myth amongst casino players is the gambler’s fallacy. A gambler’s fallacy is the belief that what happens on the current spin is influenced by what happened in previous spins. So, for example, if you believe that you are about to hit a win on the next spin because all your previous spins were a loss, you are committing a gambler’s fallacy.

Obviously, this belief is faulty because each spin is independent of the rest and is not influenced by what happened or did not happen previously.

Are Slot Machine Jackpots Random?

Yes, slot machine jackpots are random. All regulated slot machines produce random results due to the RNG software. So, all the jackpot wins were completely random. Some people may feel like slot machine jackpots are not entirely random due to the rarity of winning them, but that is due to their low winning odds.

Additionally, jackpot slot machines tend to have lower RTP rates compared to other slot machines, which means the potential jackpot payouts may be harder to hit.  

What Happens If You Hit Jackpot On A Slot Machine?

If you happen to be the one-in-a-million slot machine jackpot winner, a number of things may happen. First, congratulations! Depending on the jackpot size, your payouts may come directly from the casino or the game provider.

But, before you can count the zeroes in your account, the casino may need to verify your personal details and other important details they may need to ensure you are who you claim to be. They will also verify that you did not violate any terms and conditions. 

If everything checks out, the whole amount may be in your casino account if it is a small portion. But, withdrawing it into your bank account may not happen in a single lump sum because casinos may have withdrawal limits. If the withdrawal limit is less than your jackpot, then you may need to withdraw it in instalments over a few weeks or months. It could even stretch out to a year and above, depending on how big it was. 

However, if the amount comes directly from the game provider, you may receive it in a lump sum, depending on the provider.


In conclusion, slot machine jackpots are possible and have happened, even if the odds of winning them are significantly lower than on a standard slot machine. And the best part about them is that they do not need any skill, strategy or tricks. You just spin the reels and let the RNG software do its thing.
