About Golden fishtank slot

Golden fishtank slot featuresIn Golden Fishtank you get to experience what it's like to slowly swim around in an aquarium. You will get acquainted with various aquarium fish that seem to thrive among the corals and try to easily look for the treasures hiding at the bottom. Incidentally, we should say that it is a completely huge aquarium the little crabs are splashing around in. The aquarium is not exactly a goldfish bowl!

The graphics in Golden Fishtank are delightfully colorful. In fact, the game as a whole with its graphics, its animations and its sounds is a beautiful and harmonious story. It is a slot for those who like quiet slots that have neither epilepsy-inducing graphics nor a cacaphonic sound. Golden Fishtank offers peace and quiet and a relaxing game pace.

In terms of gameplay, Golden Fishtank doesn't offer any major thrills. The game has five reels and three rows with a total of 20 fixed paylines. If you have tried others Yggdrasil slots previously, you immediately recognize yourself in the concept. Three in a row wins and you have plenty of wilds to use to hit wins. In the free spins bonus, however, there are some more special concepts to the game mechanics and they are of a clearly delicious nature. Read more about them below.

Stakes and winnings

In games from Yggdrasil, you only very rarely need to adjust coin values and bet levels separately. The game developer seems to have the idea that it really shouldn't be an art to set the games spinning. To play at Golden Fishtank you just need to click on the desired coin value. This value is then multiplied by the number of lines. The coin values range within the range the casino sets which means you play for within the range the casino sets per spin.

However, there is one small detail to keep track of. Just to the left of the spin button you will find a button labeled “+5”. A click on this activates Golden Bet It is a feature that allows you to get an extra feature in the free spins round. The cost is one-fifth of your basic effort. For example, if you play with an amount set by the casino as a bet, the bet will be an amount set by the casino with Golden Bet activated.

In some slots from Yggdrasil you can win astronomical sums. Valley of the Gods is a good example. Here you can play home as much as 580,000 coins. In other slots, the maximum winnings are significantly more modest. In Golden Fishtank, the maximum win on a single spin is 10,000 coins, which is not so impressive. At the same time, it is far from any impossibility to meet such a profit.

Golden Fishtank RTP is 96.80% over time. It is a figure to pay a little extra attention to. The game is the one from Yggdrasil that pays by far the most on average!

Symbols

Ten symbols are combined on the five reels. Two of these are special symbols and it involves a wild and a free spins scatter. Four aquarium fish act as high-win symbols while four suite symbols (hearts, spades, clubs and diamonds) are low-win symbols. However, in fairness, it should be said that the difference between the two categories of paying icons is not so great. It is the green-yellow fish that is the game's highest paying. Five in a row with this pays 250 coins.

Functions

In the base game there are wilds and scatter symbols. In the bonus round, however, significantly more special symbols can appear. Here is a summary of Golden fishtanks bonuses.

Wilds

The Wild symbols in Golden Fishtank may not be graphically the most impressive. The symbol consists only of the text “wild”. However, its usefulness should not be underestimated. You get wilds on the reels in every second spin and not infrequently it is with the help of them that you scrape home winnings. There are few slots that are as generous with the jokers as Golden Fishtank. It's probably just NetEnts Secrets of the Stones and Secrets Of Christmas that can board Yggdrasil's slot.

If you get wilds on a complete line, which is not entirely impossible with the generous number, the Joker pays as the highest paying fish symbol.

Free spins

The second special symbol is a classic Free spins scatter. However, it is not Classic in the aspect that it brings cash winnings. With three or more free spins symbols with a cheerful real goldfish as a motif, you win free spins but unfortunately you do not get a cash win.

With exactly three scatters you win 6 free spins. You can also click on a total of three features. Four scatters give 8 free spins with four features while five scatters give 10 free spins with 5 features. If you have also activated the Golden Bet, you will receive another click.

Which features you get to play with is determined randomly. You cannot choose freely. Instead, you should click on objects that float up from the bottom of the aquarium. Each item you click on gives you a feature. The total of six specials are quite different among themselves. The ones you can click through are the following:

Extra free Rounds – 2 or 4
Multiplier - 2x on all wins
Random wilds-1-2 are added at random locations in each spin
Sticky wilds-1 wild is placed on a random position and stays there
High bars – one of the fish symbols becomes significantly more frequent on the reels
Fish Wilds-one of the fish symbols acts as extra wild.

The latter special is the clear highlight for win potential. It can give you really big chances of landing big wins. If it is paired with “high bars”, it is even better. If you get to field all six special players together, the free spins bonus round can be a particularly lucrative feature.

Summary

Golden Fishtank has the character of a slightly simpler fruit machine with its colorful graphics and simple game idea. At the same time, there is a depth to the game that means that it offers so much more than a fruit machine can do. However, it goes without saying that the biggest entertainment comes in the free spins round and we probably think that there is a little too much focus on it. The game can become somewhat boring if it goes too far between the free spins activations. That the payback (RTP) is so high for being a video slot from Yggdrasil, however, is a very big advantage.
