What is a progressive jackpot?

A progressive jackpot is a prize pool that grows with each bet placed in a slot. A portion of each player’s bet is added to the pool, and the jackpot amount increases until someone wins it.

After winning, the amount is reset to the base level and starts to grow again. Such jackpots often reach millions and can fall out randomly or when certain conditions are met in the game.

What are the chances of winning the jackpot in slots?

Let’s calculate the chances of an ordinary player winning big in jackpot slots. Take the Mega Moolah game as an example.

Here is the official data about the slot, on the basis of which we will make calculations:

• RTP is from 88.12%, of which 5.3% goes to the jackpot fund.
• There are 4 jackpot levels: Mini, Minor, Major and Mega.
• The Mega Jackpot starts from €1,000,000.
• The jackpot bonus is triggered randomly, with an increased chance depending on the bet.
• Minimum bid: 0.25 euros.
• The average settlement rate is 1 euro.

Based on the analysis of thousands of spins and data from online casinos, experts estimate the chance of launching the Jackpot Wheel as:

1 in 18,000 – 1 in 25,000 spins.

This is an average chance, assuming a bet of about 1 euro. With higher bids, the chance increases, with a minimum, it decreases.

There are 20+ sectors on the jackpot wheel, of which only one leads to the Mega Jackpot. The rest belong to Mini, Minor or Major.
The chance of hitting the Mega Jackpot after the bonus is launched is about 1 in 20.

If you combine both stages, you get about 1 chance out of 400,000 spins if the bet is 1 euro. At a rate of 0.25 euros, the chance may be 4 times lower (1 in 1,600,000).

How do jackpot slot machines work?

There are three types of jackpots — fixed, local progressive and network progressive.

• Fixed — does not change. For example, it is always x10,000 for the bid.
• Local progressive — accumulates within one casino.
• Network progressive (networked) — is accumulated from the bets of all players in all casinos where there is a slot. These are the ones that give multi—million dollar winnings – like Mega Moolah, Jackpot King, Dream Drop.

The progressive jackpot accumulates from each bet. That is, in each spin, part of the bet (for example, 5-10%) goes to the jackpot fund. It works like a “common piggy bank”. The more players there are and the longer no one wins, the higher the prize amount becomes.

In many progressive jackpot slots:

• the higher the bet, the higher the chance of getting into the draw.
• But even the minimum bet can win, it’s just that the chance will be less.
• In some games, the jackpot is only available at the maximum bet (more often in older slots like Jackpot Giant).

But jackpot slots work according to the same principles as regular slots. They use a Random Number Generator (RNG) — that is, the result of any rotation is completely random. Casinos and providers do not know who will win the jackpot and when. Math and chance decide everything.

How is the honesty of a jackpot game determined in a casino?

All jackpot slots are powered by an RNG random number generator. This is a software algorithm that ensures that each spin is completely random and independent of the previous ones.

Independent laboratories (for example, eCOGRA, iTech Labs, GLI) check the operation of the generator. They test the RNG and issue certificates. These tests are required to obtain a license from regulators.

In slots such as Mega Moolah, Jackpot King or Dream Drop, the jackpot is generated on the provider’s servers, and not in a specific casino. It means:

• The casino does not control and cannot interfere in the drawing.
• The winner is chosen randomly among all the players on the network.

For example, Microgaming even kept a public list of Mega Moolah winners on its website. This increases trust and transparency.

10 tips for playing the Jackpot Slot

If you want to win big in jackpot slots, here are 10 tips on how to do it.

• Choose only licensed casinos. Play only in licensed online casinos (for example, MGA, UKGC, Curacao). This is the only way to be sure that the jackpot can actually be won and received.
• Choose slots with the official progressive jackpot. These networks accumulate from players all over the world, which means that the prizes are really big and real.
• Play at a bet that gives you a chance to win the jackpot. Some slots require a maximum bet in order for the jackpot to be available. In others, the chance increases with the size of the bet, but even a minimal one can work. Always check the conditions.
• Understand the volatility. Jackpot slots are almost always highly volatile: winnings are rare, but large. Get ready for a series of “empty” spins and use your balance wisely.
• Set a budget limit. Decide in advance how much you are willing to lose, not hoping to win back. The jackpot is a lottery with millions of participants.
• Playing on a car spin is normal. The probability of winning is the same, both manually and on the autoplay. The main thing is to keep an eye on the budget.
• Follow the jackpot progression. Some players prefer to enter when the jackpot has exceeded the usual level. This does not increase the chances, but it seems psychologically beneficial.
• Study the slot before playing. Find out how the jackpot is activated, whether it can be bought, what bets trigger it, and whether there are bonus chips other than the jackpot itself.
• Don’t forget about RTP. The RTP in jackpot slots is often lower because a portion goes towards accumulating the jackpot. It’s a price to pay for the chance to win millions.
• Don’t consider the jackpot a way to make money. The jackpot is pure luck. The game should be an entertainment, not a way to earn money. Always remember: big wins are very rare, but they are real.
