About Medusa Castle

NextGen Gaming despite the fact that the game developer is a giant internationally, it has not really made it in Scandinavia. However, this does not mean that the developer does not create game-worthy slots. It's just that developers like Yggdrasil , NetEnt and Play'n go, so to speak, are ahead in the queue. The slot that is probably the most famous and thus also the most played in NextGen gaming's range is Medusa . The game was released in the summer of 2011 and it did not take many weeks before it sailed up as a big favorite of many.

When Medusa was released, the game really was state of the art with 3D elements, a very wide soundstage and a plethora of special features. We think the game has aged well. There are significantly newer slots that look to be significantly older!

In Medusa, everything is about ancient Greece and its myths. Medusa watches over the game screen and we can hear her snakes hiss in the background. The sound effects are many and they are dramatic in nature to say the least. The idea is for us players to make a visit to Olympus on an ominous night when the gods are angry and the humans do best to stay inside. Take a closer look at our free game above to see what we mean!

In this context, it may be worth saying something also about the castles of Medusa II. It is a pure sequel to the 2011 version and the game was released in 2014. Here we are offered more of what makes the original so popular. The graphics are even better and the special effects even more dramatic. In Medusa II you have 243 ways to win, but otherwise the games are pretty similar. One thing to note in particular, however, is that the refund rate (RTP) for Medusa II is a whopping 97.07%. That figure is sky-high above the original's 95.42%.

Stakes and winnings

Medusa is an easy slot to spin. Across the five reels and three rows you will find a total of 25 paylines and you bet between 0.10 – 25$ per line. If you want, you can also adjust the number of paylines. However, it is not recommended because you risk getting a lower RTP.

Medusa RTP is 95.42%. It's hard to be impressed by that figure, but at the same time it should be said that the slightly higher variance of the game allows you to get a significantly higher (or lower) payback during individual game sessions.

The maximum win in Medusa is 10,000 coins. In concrete terms, this means that you can win between$ 1,000 – $ 250,000 depending on the bet you play with.


On the five reels of Medusa there are nine regular paying icons. They pay really well overall, and the ”palace symbol” and ”warrior symbol”, for example, can alone bring winnings of several thousand coins. In addition to these two high-win symbols, a gold coin (depicting Medusa), a snake, grapes, arrowheads, winged shoes, jewelry and amphorae are featured on the reels.

In addition, there are no less than four special symbols. It's about a scatter, a superspins symbol, a bonus symbol and so Medusa herself. What she does, you can read more about below.


There is unrest on Olympus and the reason is that the Gorgon Medusa is on the$igstigen. She wants to challenge the gods and enchant all her enemies. A glance from her green eyes is enough for the poor poor man who watches her to turn into a stone pillar. Medusa is packed with features to say the least and playing is a bit of an adventure. You never know what will happen in the next spin. A little snopet is just that it is not always that the special features give any major dividends.


There are no actual regular jokers on the reels of Medusa. Instead, we'll have to wait for Medusa to show up. If she appears in three positions on the screen in a single spin, a delicious respins feature is activated. You will then get three re-spins played with expanding jokers (Medusa in full figure) and a multiplier of 3x. the expanding Joker will appear either on reels 2, 3 or 4.

Scatters and free spins

The logo for the game is scatter. It is a classic story that pays a cash win (between 2-250 times the BET), and activates ten free spins. During the free spins bonus round, all wins are doubled.

If a soldier with a sword appears in the free spins round, you win between 1-3 Super spins and then all your winnings will be multiplied by a factor of 5x. the Super spins are played after all the ”regular” free spins have been completed.

Pegasus Bonus

When, then, does the winged horse Pegasus come into the picture? Well, he is on all reels and should he appear on at least three positions in a single spin, you win access to a simple bonus game where you have cash winnings to play home. You should then simply click on any symbol. With a little luck you then get to choose again and with even more flax you win all the cash prizes that are available to pick up. The maximum win in this bonus round is 50 times the bet.

Double or double

NextGen Gaming has also stopped with a classic kvitt-or double-feature. The game idea is simple. Choose red or black for a chance to double your win or choose suite for a chance at quadrupling.


The popularity of Medusa can be attributed partly to the very deliciously presented theme, partly to the huge amount of special features. If you are a fan of history in general and Greek antiquity in particular, Medusa can be a really good choice. We just ask you to pay attention to the fact that the RTP of the game is in the lowest team. If you like the game, it might be worth taking a closer look at the sequel Medusa II.
