Types of Jackpot Games

Slots with progressive jackpots are the big boys that can offer huge prizes and they build and grow every time someone plays them. These magic slots tend to be based across multiples gambling websites and even multiple software companies. This way, they can grow very quickly. Sometimes also known as “Linked” Jackpots, they can build for weeks and months at a time, growing to truly staggering proportions. 

Daily Jackpot slots are games sometimes known as “Must-go” or “Must-fall” Jackpot games, depending on the casino, and have a daily prize that must be won, usually at the same allotted time each day. The prize pots tend to be smaller than Progressive slot machines ones but they are more regular and can still deliver decent bang for your buck.

Fixed Jackpots can be found on all slots and they never change. They usually require 5-of-a-kind symbols to land or for you to complete one or more several bonus rounds, but you know the value of them when you start. 

King Jackpots. Here for each game linked to this jackpot, 0.25% or more of your stake per spin goes towards increasing the jackpot prize pool and reserve jackpot. Unlike other jackpot games, the starting value (or seed) isn’t affected by each game but is funded only once per active jackpot.

How to hit jackpot on slots?

  1. Choose slots with high payouts: Look for slots that offer high payout percentages, typically around 95% or higher.
  2. Bet maximum coins: Most slots have a maximum bet limit, and you should always bet the maximum number of coins allowed. This increases your chances of hitting the jackpot as many slot machines only offer the jackpot when the maximum bet is placed.
  3. Manage your bankroll: Set a budget for your gambling and stick to it. Do not chase losses or bet more than you can afford to lose.
  4. Play progressive slots: Progressive slots offer larger jackpots that increase every time a player places a bet on the machine.

Progressive Slots – Top Real Money Casinos with Progressive Jackpots

The Progressive Jackpot is the acme of the top UK online casinos. The Everest every punter wants to scale. Progressive Jackpots aren’t contained by just one casino or even one particular territory; they grow every time they are played and are often fed from across a vast panoply of online sites, spanning continents and multiple time-zones. Whilst any Jackpot win is to be welcomed, Progressive Pots truly capture the romance and fantasy of casino wagering.

From the meekest punter with minimal means, right up to the whale and their bottomless resources, Progressive Jackpots are available to all. Democracy manifest if you like! Here are some of the best online casinos out there providing Progressive Jackpot games.

How Progressive Jackpots work

Very simple; each spin adds to the pot. There is a minimum qualifying stake, which must be met to qualify, but it is usually a modest amount, from as little as 10p a spin. With tens of thousands of players contributing to the pot at peak times, the Jackpot can grow very quickly. Winning it is the tricky part, but as it is always randomly generated, it is open to all players. Once it has been won, it then resets to its allotted starting point and the whole process starts all over again.

The big win is usually started by triggering a bonus feature on the game. These include Free Spins, landing special symbols and other Bonus features like Scatters and Wilds. Whilst the calculated odds of winning the lottery are 300 million to 1, the odds of hitting the Progressive Jackpot on a slot game are a mere 50 million to 1.
