Slot machines are gambling games with spinning reels that feature colorful symbols.  When we say slot machines or the modern online slot, we refer to 3-reel slots, 5-reel slots or video slots, 3D slots, and progressive or jackpot slots.

With slots, players set the wager, spin the reels, and if it lands at least three matching symbols, it earns a payout! There are different slot machines, but progressive slots are among the most popular.  This guide will discuss its design, features, and why you should play these games in top Bitcoin and crypto casinos!

What are Progressive Slots?

A progressive slot is a special slot machine offering huge jackpots, with prize pools increasing with every wager added to its systems. These are called ‘progressive slots’ because the jackpot prize increases with every bet until someone hits the winning combination. It’s a casino game that works for both players and operators looking for big wins and an engaged set of players. In many casinos, it’s common to have progressive slot machines with at least $100,000 in jackpot, with some premium titles offering at least $1 million in seed jackpot!  Some popular progressive slots games are Mega Moolah from Microgaming and Divine Fortune and Mega Fortune from Netent.

How do Progressive Slots Work?

Are you wondering how to play progressive slots? Progressive jackpot slots typically have three major features, which we explain below:

The Contribution

For every bet you wager, a small portion is shaved off into a separate pot used to fund the jackpot or jackpots, as the case may be. Some games take 3% of your bets, and others take less.

How to win the jackpot?

Like regular slot machines, progressive slots aim to match all five bonus symbols to win the jackpot. In some online slots, matching all five Wilds will do the trick. Once a player lands all five Bonus symbols (or Wilds, or any Special Symbol as indicated in the paytable), the jackpot is won, and the jackpot amount returns to the ‘seed’ amount. 

Notably, most progressive slot jackpots aren’t fixed — they keep increasing with every contribution made until a winner emerges.


After a lucky player wins the jackpot, the jackpot resets itself to a seed amount and restarts the contribution process. This process is called seeding. The seed amount is the aggregate of the first amount all players contributed. It can sometimes be a massive amount of money if the slot has thousands of players contributing to it.

Tips on How to Win Progressive Slots

Pay attention to RTP

Return-to-player value (RTP) is a ratio that shows the probability of the game returning your bet in an unlimited number of spins. The ratio is always expressed in percentages. If you want to increase your chances of winning a slots progressive jackpot, stick to games with a higher RTP. Also, note that your chances are only higher in the short run. As you continue playing, the casino’s house edge will kick in and increase your risk of loss.

Loss limit

Setting a loss limit can help you enjoy playing a progressive jackpot slot without being under financial pressure. It is advisable to stop playing once you hit the bankroll limit. In addition, you can also set a budget for progressive slots and another for different casino games. This strategy allows you to fully enjoy the diverse game selections of your preferred online casino.

Choose your casino wisely

Casino games are nothing but software and a bunch of codes. Many companies build the algorithms that run slot games. Therefore, like other software, there’s a slight probability that some games may be tweaked in favor of the operator. As a player, make sure to play in reputable crypto casinos with top software vendors and rely on a Random Number Generator. 7Bit Casino of Dama N.V., for example, only works with trusted software vendors that rely on games with random outcomes. Bitstarz Casino is another trusted destination for online casino games, and it features an impressive selection of fair progressive slots.
