Megaways slot machines - specially developed and a hit with casino fans

Megaways slot machines are an interesting feature in the world of casinos. The manufacturer Big Time Gaming has focused on innovative ideas to offer players an even more exciting gaming experience and increase the chances of winning.

The Megaways slot machines have six reels and many of them also have horizontal reels. This combination can result in up to seven symbols per spin, which makes for a particularly dynamic gaming experience.

The unique concept of Megaways Slots is based on a variable number of paylines, which can allow up to 117.459 different wins. Some of the most popular slots 2023 in this area are:


What makes the Megaways games so special?

Australian games developer Big Time Gaming designed the Megaways slot machines with the aim of developing a new concept for paylines. This project not only succeeded, but it also revolutionized the game selection of online casinos. Unlike traditional slots where the number of paylines is fixed and unchanging, Megaways paylines can increase up to 117.649 ways on each spin. This flexibility means that the outcome of the game is always unpredictable, making the gaming experience even more exciting.

The Big Time Gaming System is now available in many cooperations such as NetEnt, Pragmatic Play and many other manufacturers. The Megaway games not only offer excitement due to the variable number of ways to win, but also due to the numerous bonus games and features. Every developer implements his own ideas here. In most cases there are free spins rounds with different win multipliers. In addition, random bonus games are often integrated into the base game and offer additional chances of winning.

Payout percentages and volatility in online slot machines

RTP – Payout Ratio

A uniform payout rate cannot be set for Megaways Slots, as this can vary depending on the game. There are slots with both higher and lower average payout percentages.

As a rule, however, the Return to Player (RTP) values ​​of most Megaways slot games are in the range of 94% to 96,5%. This roughly corresponds to the usual RTP values ​​found in online casinos. A fixed value cannot be specified, these are guide values!

volatility

The volatility of slots with Megaways is enormous. If you're looking for a slot that spreads the wins evenly, stick with the classic 10-payline slots. At Megaways, on the other hand, winnings can wash into your coffers like a storm.

However, there is also a flip side to the coin. Players often have to play through long losing streaks without significant wins. The actual party usually only starts in the bonus feature.

Advantages and disadvantages of online slot machines compared to classic slot machines in the casino

A big advantage of online slots is that there are no opening times. You have access to the slots at any time. However, this can also be a disadvantage, as the threshold for possible gambling addiction is lowered. It's important to keep track of your own behavior.

Game selection

Slot selection is limited in casinos. Many of the slot machines here are true classics that haven't been improved or replaced in a long time. However, when it comes to variety, then you are on the safe side with online slots.

Bonuses and Offers

In order to win new customers and keep existing customers, numerous online casinos now offer bonus payments or free spins. This is of course an advantage for players, because in this way they can see very well which slots appeal to them.

Surroundings

Most online slots are played alone. While the community is more extensive and many online casinos also offer forums and multiplayer slots, it is often said that the human component in the on-site casino is not to be underestimated.

gaming experience

The feeling conveyed in a game library is incomparable. The colors, the smell and the flair are unique. While an online casino mimics this, many users report that it's not the same. Here the slot machines in the casino are at the forefront.
