Review of the Atlantis Thunder’s performance on St. Patrick’s Day

Theme and plot of the story

It’s impossible to tell what was going through the minds of Kalamba’s executives when they decided to release this Saint Patrick’s Day-themed sequel to Atlantis Thunder on the big screen.

While both Ireland and Atlantis are lovely regions veiled by the mists and waves of the North Atlantic, one of them is a real member of the European Union, while the other is a legendary drowned country that has never existed.

Atlantis Thunder: St. Patrick’s Day, on the other hand, has a green top hat on Neptune, all of the sharks have turned their backs on Tullamore, and there are no sea snakes in the Atlantic Ocean.

Graphics, sounds, and animations are all included.

The visuals are of the highest quality. Well drawn and well animated, though perhaps a little cold and characterless.

Aside from that, the reels do conceal the background in an unusual fashion, as seen by the little sparks of life in the water around the game, which suggests that a significant amount of work was put into animating the otherwise indistinct backdrop.

The sound effects are good, and the symphonic and choral soundtrack is quite immersive, conveying the sluggish drifting currents of the undersea world rather as the bustling Donnybrook that is St. Patrick’s Day. The film is rated PG for language and violence.


The game is played on reels that are organized in a 3-4-5-5-4-3 layout, and it is a win-any-way method. With those numbers in mind, you have 3600 different possibilities for fishing lines, which is plenty of options for catching fish.

Additionally, there is a system of progressive Jackpots that may be won by landing a combination of Jackpot (Poseidon) symbols and Wild symbols on the reels.

Getting ten or eleven of these symbols combined on one spin wins the Silver Jackpot, twelve or thirteen wins the Gold Jackpot, and the Platinum Jackpot goes to the person who obtains fourteen or more Wild and Jackpot symbols combined on one spin wins the Platinum Jackpot.

Each stake generates a 4 percent commission, which is divided among the three prizes.

Wilds, bonuses, and free spins are all included in this game.

The Wild symbol may be used to replace any other symbol with the exception of the Bonus sign.

Some Wilds are equipped with x2 or x3 multipliers, which let them to count as two or three symbols, respectively, for the purposes of forming winning combinations and contributing to jackpot prizes, depending on the game.

When you hit three or more Bonus symbols, you will be sent to a free spin bonus game. Depending on how many Bonus symbols you acquire, you may earn anywhere from 8 to 20 free spins, which can be re-triggered many times.

During the free spins, all Wilds get multipliers of x2 or x3 linked to them.

Bet sizes, return on investment (RTI), and variance

With a maximum return to player of 97.73 percent, this game offers a substantial amount of value to players.

It is unclear how the various features affect the return to player; however, it is most likely that the minimum return to player of 96.66 percent will be achieved by playing the base game normally, and the maximum return to player will be achieved by purchasing direct entry into the highest value bonus round.

There was a variety of bets available on the site we reviewed, ranging from $0.60 to $/£/€300.00. However, if you want to participate in the extra games, this figure might be far greater.

The volatility of this game is medium-high, which suggests that it may be played successfully with our chosen techniques.


Atlantis Thunder: St. Patrick’s Day is a visual delight, although the seaweed may not be as green as it seems on first brush, according to the captain.

Even if the return to player is respectable at the lower end of the spectrum and very tempting at the upper end, it is impossible to predict which version of the game will provide that 97.73 percent return to player.

The progressive jackpots are a significant draw of this game, and if jackpot-style slots are your thing, this could be the best slot machine to play to fulfill your needs in this category. Aside from that, we recommend that you try fishing in a different pond.
