What to Look for When Choosing a Jackpot Casino?

Shopping for a jackpot casino requires some care. There are many online casinos that offer jackpots, but not all gambling sites are legitimate or safe. Read our must-dos before you jump into an online casino and go hunting for local progressives.

Gambling Licence

All slots sites and casinos must be covered by a valid gambling license. This ensures that the casino is properly operated and overseen by a regulator. It also means that you can be sure that payouts will be made accurately and on time.

Random Number Generators

RNGs determine the outcome of every slot spin. The process is completely random, whether you’re playing on mobile or a desktop PC. Reputable online casinos will regularly test their slots via external auditing labs such as eCOGRA. Some of the top casinos will even display testing certificates as proof.

Safety and Security

All licensed and regulated casinos use the latest safety and security measures, such as SSL encryption technology and firewalls. These can easily be verified by looking for a little padlock icon in the address area of your preferred web browser.

Casino Bonuses & Promotions

Most online casinos offer some form of a welcome bonus. This can entail a match deposit bonus, free spins, cashback, or a combination of all three. We always check the size and fairness of all online casino bonuses. Is the minimum deposit requirement enough, and what are the wagering terms like?

Terms and Conditions

The terms and conditions of a casino bonus can make or break it. High wagering requirements can make an online casino bonus pointless, so we always check the details on every site. The average-industry standard for wagering requirements hovers around the 35x range.

We also check game contribution rates. Progressive jackpot slots tend to be ineligible toward clearing a casino bonus. Always check the terms and conditions page before you opt in to play online jackpot slots.

Choice of Payment Methods

Good casinos accept a wide range of payment options. You hit those progressive jackpot games by loading your account with fiat currency or cryptos like BTC and ETH.

You should also check the minimum and maximum deposit and withdrawal thresholds. Some casinos have reasonable minimum deposit and withdrawal amounts. However, other gambling sites impose steep minimum withdrawal limits, which makes it hard for low rollers to cash out their jackpot winnings. Read our guide on how to deposit money safely at casinos.

Some casinos that accept Bitcoin offer unlimited withdrawal limits. That’s what makes progressive slots so enticing. Always check the cashier so you know what the limits are.

Choice of Jackpot Games

Always check the casino lobby to see what the choice of games is like. You won’t find every jackpot game in the online casino industry. However, there should be a decent selection of game themes and types. And of course, you should understand how progressive jackpot slots work before you sign up and play.

VIP/Loyalty Schemes

Some casinos run VIP programs for high rollers. You can also earn comp points by playing slots with a fixed jackpot. Rack up points for playing your favorite games and redeem them for perks and cashback. High rollers can also enjoy bigger gifts such as expedited withdrawals and birthday bonuses.

Types of Jackpot Slots

There are many different types of jackpot slots available on the market. Some jackpots are won at random but also look out for Must Drop Jackpots which are set to a strict expiration period. The types of progressive slots also largely depends upon the type of software provider offered at the casino.

Hot Drop Jackpots

Hot Drop Jackpots are a relatively new type of jackpot. They are available at Cafe Casino among others. Hot Drop Jackpots encompass three types of jackpots, with prizes dropping hourly, daily and when reaching a specified amount.

The hourly fixed jackpot totals around a few hundred bucks, but the Super Jackpot drops at a cool $250,000. Look out for some of our recommended Hot Drop slots such as 777 Deluxe Hot Drop Jackpot, Reels of Fortune A Night with Cleo and Lady’s Magic Charms.

Local Jackpots

Local jackpots are prizes that are tied to one online casino. The prizepool is generated from bets placed by players at that specific casino.

The maximum payouts are usually smaller than those you’ll find at wide-area progressives that may cover multiple casinos. However, the jackpot can grow with more bets put into it. This gives it an edge over fixed jackpot games.

Wild Casino runs a multitude of local jackpots, including BetSoft’s 3D games, Faerie Spells and Greedy Goblins.

Progressive Jackpots/Pooled Jackpots

Progressive jackpots are the most popular type of jackpot available at online casinos. Progressives are not fixed jackpots but can continue to grow until you take one down. Plus, the longer the jackpot goes unclaimed, the bigger it gets.

RTPs on progressive slots tend to be low due to their high jackpots. For example, the popular progressive jackpot Mega Moolah has a payout percentage of 88%, yet regularly breaks records for its jackpots. 

Fixed Jackpots

Fixed jackpots do not grow in value. There may be several levels of fixed jackpot which you unlock by triggering a bonus game. These are generally divided into Mini, Minor, Major and Mega. The higher your stake, the more fixed jackpot levels you can unlock.

Some of our favorite jackpot online slots include 5 Wishes and Aztec’s Treasure by Realtime Gaming. Play them now at Red Dog Casino.

How Do Jackpot Slots Work?

Jackpot slot games work in a different manner depending on the type of game you are playing. Progressive slot games have a starting seed value. Each time you make a bet, a small percentage of the wager goes toward the cash pot.  The prize keeps on growing until you finally strike it lucky.

The jackpot seed amount varies from one slot game to another, and it is up to the software game developer to make the prize as attractive as possible. For example, Microgaming’s Mega Moolah and Wowpot game series come with a 4-tier progressive jackpot feature. The top jackpot prize can start at $1 million.

Even though there are many types of jackpots, all slots use a random number generator to determine the outcome. There’s no real trick to winning, but generally the higher your stakes the more chances you have of triggering the jackpot game.

How Are Progressive Jackpots Paid?

Won a big progressive jackpot? Some casinos will pay out the prizes in installments, while other casinos may recommend that you invest the prize money.

The prize money does not come from the online casino you are signed up to. On the contrary, progressive jackpots paid come from the software game developer.

Slots with Incredibly High Payouts

Only a handful of online slot games have the popularity and jackpot potential to break records. You can view the current jackpot by checking the casino lobby. The jackpot tracker displays the current value of the unclaimed prize.

Remember, all slots offer a regular jackpot within the base game. The fixed jackpot is paid out if you hit 5-of-a-kind during a spin. Fixed tiered jackpots like Mini and Minor are usually displayed above the slot reels.

Are Jackpot Slots Fair and Audited?

The best online casinos always ensure their slots are independently tested by approved labs. Look for the testing lab logo at the foot of the online casino lobby. Offshore casinos tend to use their own testing labs, although if the casino uses GLi or eCOGRA, all the better.

  • Play land-based exclusive progressives such as Megabucks

How to Improve Your Odds of Winning a Progressive Jackpot

All progressive slots are random and as such are games of chance. You never know when a jackpot will trigger but there are ways to enhance your chances of winning:

  • Pick the right game: Know the game’s payout percentage and volatility levels. Jackpot games are notorious for being highly volatile, but a higher payout percentage could give you bigger wins.
  • Play at bigger stakes: You may have a bigger chance of hitting the jackpot if you play at higher stakes. This affords you more “tickets” with a shot at activating the prize pool or triggering one of the special bonus games.
  • Know the stats: Check the history of the game and how often a progressive jackpot win has been triggered.
  • Play for free: Before putting your own money on the line, play the slot game for free. The best free slots are identical to their real-money counterparts, allowing you to familiarise yourself with the paytable and gameplay.
  • Claim a bonus: If you want to make your bankroll stretch, claim a casino bonus, but be aware of the terms and conditions of the bonus in case jackpot games are exempt.
  • Have a set win/loss limit: Whether you hit a big win or lose all your bankroll, know when to walk away. Don’t make more deposits to chase after your losses.
