Theme and Graphics

4ThePlayer’s 3 Secret Cities slot has an intriguing Aztec theme . Players are taken on an adventure to discover lost worlds and hidden treasures, as stunning stone pyramids, sunken statues and lush greenery serve as the game’s backdrop.

Impressive Character Design

The game’s two main characters are a priestess, dressed in a colorful and ornate costume, and an intrepid explorer. The rest of the game’s symbols feature all sorts of items you’d take on adventure, like maps and compasses, along with the kind of beautiful treasures you’d expect to find in any of these secret cities.

3 Secret Cities is definitely one of the most eye-catching slot games from 4ThePlayer. There is a very impressive attention to detail in this game, and the colors are just so vibrant.

Big Reel Portrait Mode

Big Reel Portrait Mode is a special setting exclusive to 4ThePlayer slots that optimises your gameplay experience for play on mobile devices. This allows the reels to take up a larger space in portrait mode, with the reels spinning right to left – but, the gameplay works in exactly the same way as if you were playing with the reels spinning vertically.

You can switch in and out of Big Reel Portrait Mode through the options menu.

We love it when an online slot caters to players in portrait mode. How often does any use a mobile device in landscape?!

4ThePlayer really does have the player in mind when putting together its slots and coming up with unique features. So, we're happy to play any slots that feature Big Reel Portrait Mode.

RTP and Variance

4ThePlayer's 3 Secret Cities slot has a payout percentage of 96.5%. If you use the Bonus Buy, then the RTP increases to 98% - but, the Bonus Buy isn’t available to players in the UK.

In terms of volatility, 3 Secret Cities is a high variance online slot. The game’s 50,000x top prize certainly suits the volatility level, and its much higher than most max wins out there at the moment. Only a few games have similar grand prizes – like Money Train 2 and El Paso Gunfight .

How to Win

There are 1024 ways to win while playing 3 Secret Cities slots from 4ThePlayer. Winning combinations are made by landing three or more matching symbols on adjacent reels.

The game’s top three highest-paying symbols pay out for two-of-a-kind combinations and higher. So, this helps to boost your overall winning potential as you spin the reels.


The free spins bonus in 3 Secret Cities is triggered by landing three scatter symbols. However , if you land just two, you’ll also open up a special bonus feature that can improve your winning potential in the long run. This is called BONUS↑UP

Two scatters will open up a pick-a-prize bonus. Here, you’ll win either a cash prize worth up to 50x, or you’ll progress along the map across all three Secret Cities.

The further you progress on the map, the bigger and better your free spins bonus will be when you manage to trigger it. There are three locations:

  • Jungle City: up to 15 free spins with a x5 multiplier and a top prize of 16,000x
  • Lake City: up to 25 free spins with an 8x mutiplier and a top prize of 30,000x
  • Gold City: 50 free spins with a 15x muliplier and a top prize of 50,000x

These numbers refer to the maximum number of free spins, top multiplier and grand prize available from the free spins round you can get in each bonus. For example, you aren’t guaranteed 15 free spins with a x4 multiplier in the first bonus.

Above the reels, there’s a little box that helps you keep track of your bonus progress. It shows you what the next perks on offer are for the next Bonus Level on the secret cities map.

Reset to Jungle City

Once you've manage to trigger a bonus, you get reset back to Jungle City. While it is the least generous of the bonus games, it is the easiest one to trigger. So, it's some consolation.

Free Spins Bonus

We're very impressed with the 3 Secret Cities slot features - particularly the free spins bonus.

When you land three scatters, you’ll trigger the free spins round – but, first, you’ll have to pick out the specifics. In this round, you’ll select from blocks to determine:

  • The number of free spins you’ll receive
  • The win multiplier that will be applied to your free spin wins
  • Which symbol will be super stacked.

Once you’ve selected those three options, there is the chance for you to win even more free spins and increase your multiplier. However, if you pick a block that reveals an X, then you’ll head straight into the free spins round.

3 Secret Cities Free Spins

This is a great addition to the free spins bonus, as it provides a whole new layer to the feature. It's exciting to pick from the options and see just how much you can improve your bonus.

3 Secret Cities Slot Review

4ThePlayer doesn’t release online slot games very often but, when they do, they bring players some great gaming experiences. Slots like 9K Yeti and 2 Gods Zeus Vs Thor present innovative gameplay features – so, 3 Secret Cities fits in well with the rest of 4ThePlayers offerings.

What really sets 3 Secret Cities apart from other slot games is that it gives players the ability to travel between locations in order to land bigger and better bonus payouts . We’ve seen this kind of “world” mechanic in games like Gemix and Hammerfall but it’s never been presented in this way before.

Advance Towards More Generous Bonuses

In 4ThePlayer's 3 Secret Cities slot, every time they miss out on the free spins round (by landing two scatters instead of three), they can advance along the map. Each step they take provides them with the ability to earn more free spins, bigger multipliers and more generous stacked symbols.

3 Secret Cities Map Bonus

When writing this 3 Secret Cities slot review, we found the Bonus UP was quite an exciting feature, as it gives players something to look forward to. You’re not just missing out on free spins bonuses when you’re landing just two scatters; you’re building a better bonus for later on.

Other Slots You Might Enjoy

3 Secret Cities is a very unique online slot, and it might be difficult to find other similar games. However, we've got you covered with a few suggestions:

  • Wild Worlds: In NetEnt's Wild Worlds slot, there are three bonus locations - just like in 3 Secret Cities. It's a little bit different as it has battle-based bonus rounds but the overall concept is quite similar.
  • 1 Left Alive: This is 4ThePlayer's debut online slot game. In 1LeftAlive, players are immersed in a zombie apocalypse and there is a great free spins bonus where special walking wilds can be triggered.
  • Gemix 2: Like Wild Worlds, Gemix 2 also features a world-based bonus mechanic. Each 'world' offers different bonuses and gameplay; although there isn't a free spins round.
