Slot machines are without a doubt the most exciting game in the casino, and with the rise of online video slots and their various features, they’re becoming more engaging and interesting with every passing day.
The hype surrounding slots is founded on a few things – the colossal jackpots, the fun features, and the sheer number of free spins and slots bonuses casinos are giving away to win you over as a player.

How Slot Machines Work
Understanding how slot machines work doesn’t require a degree in quantum physics (thankfully). There are a certain number of reels, a set number of pay lines (patterns which make winning lines), and getting matching symbols across those lines creates payouts.
It can be helpful to think of slot machines as scratch cards in motion. Each time you spin, a new set of symbols appears on the screen, and matching certain symbols in specific patterns creates wins. Of course, symbols are worth different values, so not all payouts are equal.
Slot machines are ultimately controlled by random number generators, which are what makes casino games random and fair. This means that a complex mathematical program controls the outcome, ensuring games can’t be rigged and likewise can’t be tampered with by players.
To learn more about random number generators and how they work, check out the article below.
Of course, no one software firm has a monopoly on slot machines, and each has its own unique “flavor” as such. NetEnt, Microgaming, and Playtech are three of the biggest names in the online slots scene, and between them, they have created the vast majority of excellent video slots.
Understanding how each slots software provider operates, a little about the firms themselves, and some of their best games can give you a running start when it comes time to play. After all, would you rather play a game for $0.10 per spin with no features and a jackpot worth $5,000, or a game with epic features, free spins, expanding symbols, and a multi-million-dollar progressive jackpot?
Taking the time to read about the different software providers and their best games can make that difference. Check the page below out.

#2 Jackpot 6000 (NetEnt) – Up to 98.8% RTP
Jackpot 6000 is a thrilling classic slot machine from NetEnt with a real old-school vibe. You can play with up to 5 paylines active, betting between 1 and 10 coins per spin. It is highly recommended to play with the maximum bet of 10 coins however, as this creates the possibility of triggering Supermeter mode. In this game mode, you can win a mystery prize of between 10 – 6000 coins when just 2 joker symbols land anywhere on the reels. Also, getting 3 jokers on a payline in Supermeter mode guarantees a jackpot payout of 6000 coins. When you play Jackpot 6000 with 1 – 8 coins, the RTP is a paltry 74.9% – 79.2%. Yet with 10 coins in play, the RTP ranges from 95.1% – 98.8%. The variance is because Supermeter mode is skill based, so you can directly impact the outcome.
#1 Mega Joker (NetEnt) – Up to 99% RTP
Whilst Jackpot 6000 boasts an extremely high RTP, it is just beaten to the top spot by another NetEnt classic slot; Mega Joker. Bet with just 1 coin and the RTP is an underwhelming 76.9%. Yet on the other hand, a max bet of 10 coins elevates the RTP to between 89.1% – 99%. Furthermore, it provides bigger payouts and the Supermeter mode. In Supermeter mode, you need to choose the bet level and the optimum level at which to collect your winnings. It is this element of skill which can increase the RTP. The skill component, retro style and engaging gameplay make Mega Joker a firm favourite with players.
