The biggest casino mystery of all time – are online slots random jackpots truly random?

Here and today, we tackle this puzzle and try to solve it for you. Scroll down to learn all about jackpot slots and their randomness, and see where to play progressive jackpot slots online.

Are Random Progressive Slots Better?

Progressive slot games are prevalent. You are likely to find a large and diverse range of jackpot slot games at online casinos, ranging in themes, design, and bonus features. Like all other online slot games, progressive jackpot games are very popular at gambling venues. And operators claim that these jackpots are random. But are they?

In fact, casinos are not the only ones claiming that their progressive jackpot slots online are ‘random'. The companies that are behind the online slot random jackpot games claim that as well.  And despite these claims, players cannot help but wonder: Are progressive jackpots random?

The basic idea of playing a random jackpot slot game is quite simple to understand. Alongside the base game and any additional bonus round(s) that can be triggered when playing progressives, there's more to them.

Players will also find a progressive jackpot attached to these types of casino slot games.

However, winning a progressive jackpot doesn't come about the same way as winning a standard slot.

Namely, to hit a progressive jackpot, you don't need to align matching symbols or create winning combos. Instead, to win a random progressive slot, you just need to sit down and wait. Progressive slot jackpots land randomly. So randomly that it would be possible even to win multiple progressive jackpots in rapid succession, although that's rare (but still possible).

In plain English, minimum effort is required. Just relax and watch the reels spin, or fuff about until it hits. What's more, in most cases, you don't need to play for maximum stake levels, either. And gambling small bets is always a plus, you'll agree.

It is possible for any player, at any point, to hit a random jackpot.

This is exactly what makes playing progressive jackpot slots so exciting for many players.

Increasing Your Chances of Winning a Random Jackpot

However, you should be aware that there are ways to increase your winning chances when playing a random jackpot slot.

To potentially boost your odds of winning random casino slots, you need to modify your stakes. The rule of thumb is to play for higher stake levels or put into play maximum bet spins. The system recognizes betting patterns and register an increase to the grand pot.

Divine Fortune Jackpot
Divine Fortune is one of the most popular random jackpot slots from NetEnt.

A random jackpot is for all intents and purposes a raffle. So, the more tickets you have in any raffle, the greater chance you will have of winning a prize in that raffle.

Nonetheless, increasing the bet doesn't guarantee a jackpot. That's why it's called random.

There are slot players who played for just 0.01 per spin to walk away with a huge randomly awarded progressive jackpot. On the other hand,  hundreds of jackpots have been won by players playing for higher stake levels.

But don't let the unpredictability discourage you from playing progressives. Progressive casino slots are random, and we know them as games of luck. When playing a game of chance, you're betting on hope and not skills. So, if you wanted to know if jackpot slots are random, they are, and this is the proof.

Types of Random Jackpot Slot Games

You are going to come across a few different ways in which a random jackpot slot game will award its jackpot to you.

The most common way a slot will do this is by randomly and instantly awarding you the jackpot. The drop happens at the end of any single base game spin.

Random jackpot slot games do not award its random progressive jackpot on a free spins bonus game.

There is another way in which a random jackpot slot game will award you with a random jackpot.

Some slots have multiple different-sized jackpots. Take Microgaming’s Mega Moolah series of slots. These games all share four live networked jackpots. Therefore, you're guaranteed to win one of them only when the Mega Moolah bonus game is awarded at random. And that happens at the end of any paid for the base game spin.

Mega Moolah Fortunium Gold
Mega Moolah Fortunium Gold boasts 4 levels of progressive jackpots – Mini, Minor, Major, and Mega.

When triggered, you then have to set a bonus wheel into motion. Depending on where that bonus wheel comes to a stop, it will award one of the four available progressive jackpots.

Here are all the types of random progressive jackpot slots:

  • Standalone Slots – autonomous casino slots that drop at random from any supplier with no sequels
  • In-House Progressives – branded random slots exclusive to a specific online casino
  • Jackpot Network – a jackpot series, such as the Mega Moolah, DC Super Heroes Jackpots from Playtech, etc.

Whilst you will always have a chance, albeit a small one of winning a randomly awarded jackpot when playing any slots offering one, you should never become too obsessed with winning one of them. You can track them, but don't lose yourself in them. For by focusing solely on that every rising jackpot you may lose any sense of reality and that will often lead a player to overspend!

Gamble responsibly, always.

Here's how to avoid getting obsessed with winning jackpots:

  • Set yourself a maximum limit.
  • Never exceed your random jackpot limit.
  • Look at the progressive jackpot as an added bonus.
  • Random jackpot slots do not guarantee a win to every player.
  • Huge jackpots occur only once in a while.

In other words, you are not guaranteed to win by playing the same slot game repeatedly.

Frequently asked questions about random progressive jackpot slots online.

How often do progressive jackpots hit?

This is a difficult question to answer, because progressive jackpots are random. They use RNG numbers, so no sequence of symbols or result can be predicted. Therefore, we cannot say when will a progressive jackpot hit.

What triggers a progressive jackpot?

A jackpot is triggered randomly by a winning symbols sequence, and that means progressive jackpots are also triggered randomly. Progressive jackpots have growing seeds so players always hope to trigger the progressive random jackpot as it is usually bigger than the regular fixed jackpot.

What are the odds of winning a progressive jackpot?

The chances of winning a progressive jackpot are 50 million to one. The winning odds also depend on the game, so it can be one in 50 or 60,000,000.

How do progressive jackpots work?

A progressive jackpot is a jackpot whose size grows with each bet wagered in the game. A percentage of every bet goes toward the jackpot seed, which increases the sum that the players can win. The biggest progressive jackpot win is $23.5 million, and the seed of the jackpot is $1 million.

Are all slot machine jackpots random?

Yes, they should be as they are online casino games regulated by gambling authorities. Before launch, every game goes through extensive testing to reach the market. Only when independent testing labs confirm that the game is truly random (uses RNG numbers for sequences and therefore cannot be predicted or tampered with) can the game reach the casinos. Of course, those testing labs also maintain fairness by checking the games regularly, not just once.
