Half Pixel Studio’s, Microgaming’s newest partner second release, Atlantis: The Forgotten Kingdom, has come to Casino 442.

In this review, we’ll break down the mechanics and graphics to see if this is a standout for the already dominated theme or if it will merge into the others and become forgotten…

Theme and Design


For any namesake of Atlantis, of course, the game must be set at the bottom of the ocean. Therefore, you will find the grid surrounded by seaweed, fish, coral and other typical sea features. However, it is not in the City of Atlantis. Instead, it is outside of the city, as you can see Atlantis in the distance. The soundtrack is relaxing and serene, which is the overall vibe of this slot. Atlantis: The Forgotten Kingdom will make a relaxing playthrough for gamers with the calming waters, the mermaids, fishes, and relaxing music. The mermaid symbols have an almost anime/manga quality, as they are displayed provocatively and extremely beautiful – almost cartoonish as they are so flawless!


With a 5 reel, 3-row display with over 243 ways to win, four mermaids serve as rulers of Atlantis. A betting range of 0.20 to 30.00 coins per spin, with high volatility, this could be favourable for players who would like a break from wagering large amounts and get smaller, frequent wins. However, the mermaids also act as wilds in the Wild Mermaid feature. Landing four matching mermaids on the bonus reel will activate the feature which triggers the Wild Win Multiplier. The value of the multiplier is based on which Mermaid is involved:


  • Mermaid Queen – 4x
  • Mermaid Beauty – 3x
  • Mermaid Adviser – 2x
  • Mermaid Warrior – 1x


Bonus Features


The Atlantis: The Forgotten Kingdom has a five-option bonus game for players to choose from. If there are 3 or more pearl jewellery symbols (which is the scatter), this triggers free spins, and then players are given 5 options to choose from:


  • The Warrior’s Free Spins – 20 free spins awarded. Wild Wins multiplied by 1. Up to 3,600x initial bet.
  • The Adviser’s Free Spins – 15 free spins awarded. Wild Wins multiplied by 2. Up to 4,800x initial bet.
  • The Beauty’s Free Spins – 10 free spins awarded. Wild Wins multiplied by 3. Up to 6,000x initial bet.
  • The Queen’s Free Spins – 5 free spins awarded. Wild Wins multiplied by 4. Up to 7,200x initial bet.
  • Mystery Free Spins – A combination of a random spin and multiplier component from any options above.


A good quality of this slot game is that you can choose to be a high volatility or safe volatility, depending on your gaming preference. If you land 3 scatters at any point, you are awarded 5 free spins.




Overall, we think that Atlantis: The Forgotten Kingdom is not anything drastically new and may get lost under the swathe of different Atlantis-themed slot games available out there. However, its adjustability and bonus features make it a fun experience, and you would enjoy yourself playing. Graphically design may come across as cheesy to some in this day in age. However, it isn’t dramatically offensive. I’m sure if you give Atlantis: The Forgotten Kingdom a shot, you will have fun.
