•Check out the Promotion information to see the cash drop games

•Open any of the selected cash drop games

•Spin the reels and simply wait for the pop up window signalling that you won a cash prize

•The prizes will drop randomly until the last one is won, so you can win more than once

•If a specific cash prize is no longer shown in the game, it means all have been won

Payment methods

Because Yggdrasil casinos cater to players from across the globe, many of whom use different banking systems, you should always be able to find a payment method to suit your needs.

Progressive Jackpots

Yggdrasil offer a number of progressive jackpot games, the most prominent of which is Joker Millions. The average win on that is around €2 million, whilst the biggest win of all time was more than €5 million.

In 2017 another Yggdrasil progressive jackpot, which you could play around the globe, was won by a Norwegian player. The lucky winner picked up just shy of €5.2 million.

Yggdrasil Slots

When we narrow down the choice to Yggdrasil slots alone, there aren’t more than 30 titles available so far. The limited choice is compensated by outstanding quality and mesmerizing gameplay. Yggdrasil slots belong among the greatest titles, considering the dynamic play they showcase, aligned with strong storylines and believable characters.

Developed exclusively on the basis of HTML5 technology without the presence of Java or Flash, Yggdrasil slots work smoothly on phones and tablets. The interface reacts to the touch instantly, and the loading times are cut short.

Mobile Games

Yggdrasil Gaming believes that being able to play their games on a mobile device is more of a right than a privilege. It’s why they invented iSense, a mobile specific platform for their offerings. To begin with it was mostly applied to their video scratch games, but they soon began to use it for video slots and the company’s famed Jokerizer game was the first to get the iSense treatment.

What makes Yggdrasil’s mobile game offerings all the more interesting is that they don’t release a pared down version of them as some companies do. Instead, the mobile game is exactly the same as the desktop version, except for the fact that it’s been for iPads, iPhones and Android devices. In 2017 they realised iSense 2.0, releasing all games in HTML5.

What is a Free Daily Spin?

Those players only accustomed with traditional casino slots wouldn't be aware of terms like free spins with no deposit or free spins bonus! Here at Mega Reel we are not looking to just profit from our customers, but we want to offer an exquisite experience to all. With the player who is not aware of new terminology regarding slot titles, free spin refers to the bonus promotion offers given by casinos to their new and returning players - but also to the bonus rounds that many online slots carry as part of their gameplay.

Classic slot machines used to be set in 3x3 reel set, carrying 9 symbols that tent to pay standard low value rewards. New slots online that can can be accessed after a deposit, have more than 10 symbols and also bonus symbols that unlock extra rounds, new games and a world of excitement. Below you can discover more information on the best free spins slots and other bonus rounds that are worth trying! At Mega Reel deposit required to access our free spins bonus offers and the best slot games in the market.

Free Spins featured in the Doubles Slot

When 3 or more Free Spin symbols land on the reels they will trigger a round of free spins. The number of free spins will depend on the number of symbols:

• 3 symbols - 10 free spins
• 4 symbols - 20
• 5 symbols - 40

You will have to select one of the nine regular symbols prior to launching the free spins which will be doubled every time it lands on the reels. If additional free spin symbols land on the reels the round of free spins can be relaunched.

During the round of free spins the Max Bet, Autoplay and Free Spin buttons will be replaced with Free Spins boxes and the Total Win box will take the place of the doubled symbol. The Free Spins box will show the number of remaining free spins. The doubled symbol will switch the way your reward is displayed whether in credits or coins. The Total Win box will display the size of your winnings for the free spins that have been completed.

Yggdrasil Jackpots

Yggdrasil might not be the go-to software developer for progressive jackpots, but the ones in the collection have already proved to be quite lucrative for players.

First pooled in 2015, Jackpot Millions, has landed several substantial prizes for lucky winners across the world.

Simple in gameplay, the slot is made from 5 reels and 25 pay lines and the jackpot spin feature. The latter is triggered by you landing a joker on each reel. Fill the screen with jokers and you too can be the happy winner of the next jackpot.

With missing diamonds to hunt down, Holmes and the Stolen Stones is another brilliant Yggdrasil creation. Visually it looks great, as you’d expect from the developer. But what makes it an even more exciting mobile slot, is the five progressive jackpots.

Collect the shards and glistening diamonds and you may well be underway to win one of those jackpots. To drop one, you’ll want to land 5 shards of the same colour during the free spins game.

And although the jackpots are a tad smaller here, they are more frequent making this slot an excellent choice for action-packed gameplay.

Or if you fancy some wizardry, how about giving Ozwin’s Jackpots Apprentice a try? If you can look past the fact that it’s obviously based on a certain student of Hogwarts School of Witchcraft and Wizardry, then you’re in for some potential big wins.

This progressive jackpot slot is said to dispense a tasty three-digit prize every few hours to one lucky player so, it’s always worth checking if it is you!

Yggdrasil Gaming was founded with a lot of inspiration that gets channeled properly into creative processes. These processes end up being well-rounded, top quality gambling items with names and features that attract attention.

For example, it makes it possible for players to imitate scratching a scratch card with the help of the touch technique. Tap Reels and Brag are other notable projects started by Yggdrasil Gaming.
