Progressive jackpot slots are quite common at sweepstakes casinos in the United States, and some casino platforms have introduced in-house jackpot online games. If you’re wondering what they are and how they work, keep reading to find the answers.

What are In-House Progressive Jackpots?

Simply put, in-house jackpots are slot games developed by native casino operators. Hence, the main difference between them and other jackpot slots is that they’re only available at a particular sweepstakes casino site.

For instance, a popular provider like Pragmatic Play may release and distribute a progressive jackpot slot to many platforms. That means you can play the game at different sweepstakes casinos. However, in-house jackpots come directly from a casino’s native game developers. You won’t find those titles on any other site, and that’s what makes them unique.

How Do In-House Progressive Jackpots Work?

In-house progressive jackpots work pretty much the same as regular jackpots. As you play, a portion of your coins goes into the jackpot, increasing it over time. The same applies to other players at the casinos, and that’s why these games are called “progressive.”

Suppose the casino developers specify that 5% of every play goes into the jackpot. That means the jackpot will increase by 5 coins for every 100 coins you or other players play with. So, if 100 users play with 100 coins, the jackpot increases by 500 coins.

The casino won’t most likely won’t set a maximum limit. So, the jackpot keeps getting bigger and bigger as more players spin the reels. If you’re lucky, you can hit a winning combination and walk away with a massive amount of coins.

How big can the jackpot get? From our experience, it depends on the number of players at any given time. Casinos with more users will easily record higher jackpots than those with fewer players. If you aim to hit the biggest jackpots, it’s best to play during the weekend, when many players are active.

Why Do Casinos Offer In-House Jackpots?

Casinos offer in-house jackpots to give their players the opportunity to play slots different from the regulars. It’s always fun to play exclusive games unavailable at other sweepstakes sites, and when they come with progressive jackpots, the experience gets even more exciting.

In-house progressive jackpots also help attract new players and retain existing ones. How it works is pretty simple. If you love any in-house jackpot slot, you’ll always want to play at the casino that offers it exclusively.

Likewise, other unregistered players may come across the in-house jackpot slots and want to try them. The only possible way is to visit the casino offering the games and sign up.

Are In-house Progressive Jackpots Truly Random?

In-house progressive jackpots are genuinely random. Like third-party providers, in-house casino game developers also use a Random Number Generator (RNG). The algorithm decides the outcome of each spin at random, ensuring there’s no bias. So, your chance of landing the jackpot entirely depends on chance.

From our experience, the best casinos with in-house jackpots are transparent with their slots. When you visit the gaming section, you’ll find a real-time rundown of the number of coins in the jackpot. You also get to watch it increase as more players spin the reels. When a lucky user hits the jackpot, the casino will announce it.
