3 Secret Cities slot Big Win May 2021

It hasn't been even a week after the release of the 3 Secret Cities slot, but some gambler already hit a tremendous 10,455x Big Win on the 25th of May when playing with a bet of €0.5. Let's take a closer look at that massive gain.


The player landed 3 Scatter symbols on reels 1, 3, and 5 and proceeded to the Temple Picks bonus. 11 Free Spins with a 6x Multiplier and panther chosen as the stacked symbol were awarded.


It began with an unpromising start, as spins either resulted in nothing or brought only tiny wins. The total win was only €37.5 by the 8th spin.


However, it all changed on that spin, when almost an entire grid became occupied by stacked panther symbols, which paired with the 6x Multiplier resulted in a massive €5,184 win.


The bonus ended in the way it started, and as Free Spins were over, a total win of €5,227.5 was awarded to the gambler.

3 Secret Cities Review

When we first laid eyes on 3 Secret Cities, we thought we were in for yet another dime-a-dozen mesoamerican jungle adventure. 4ThePlayers has somehow managed to avoid that cliché trap, and it’s not only because of their new innovation; the Bonus Up mechanic. Also the unique visual style, with the cartoonish animated backgrounds, combined with a subtle, yet powerful, jungle soundtrack, contributes to making this an experience out of the ordinary.

The reels are semi-transparent, making it possible to enjoy the view, and you’re kind of rooting for the bonus round not to trigger before you’ve reached the top-tier Golden City. It’s far from catastrophic if it does though, as you can walk away with solid payouts from all 3 levels. The math model is overall very decent, but hacking and slashing your way through the base game is not all that rewarding on its own.

3 Secret Cities slot Features

The Aztec Calendar Wheel is the wild symbol in this game, and it steps in for all regular pay symbols whenever it lands. Everything revolves around the ‘Bonus Up’ feature, which awards better extras and potential in the bonus round for each level. We’ll walk you through how it all works below.

You can see the current Bonus Up level above the reels to the right, and a map will roll out if you click Bonus Top Prize panel. This map gives you an overview of the possible and current progression, and there are 3 locations; Jungle City, Lake City and Gold City.

Whenever you land 2 scatters on reels 1 to 3, you’ll pick one of them to reveal an instant cash prize up to 50x, or it will progress you to the next and more lucrative location on the map. You trigger the Bonus Round when you land 3 scatters on reels 1, 3 and 5, and this takes you to the initial Temple Pick feature.

You’ll pick 1 block from each row of the “temple”, and this awards a random number of free spins, a random starting win multiplier and a random super stacked symbol. The Pick’em game ends when you pick an ‘X’, and the possible outcomes are determined by which of the 3 cities you’ve reached. Here is an overview:

Location Free Spins Multiplier Max win
Jungle City 12 - 15 x4 - x5 15K - 16K x stake
Lake City 17 - 25 x6 - x8 20K - 30K x stake
Gold City 30 - 50 x9 - x15 35K - 50K x stake

When you land scatters on reels 1 to 3 in the bonus round, you’ll pick one of them to reveal between 5 and 10 extra spins. There is no upper limit as to how many spins you can get, and you always return to Jungle City after any given bonus round has played out.

Depending on your jurisdiction, there is a Bonus Buy option available (not for UK players). This gives you 3 options to choose from if you’re eligible, and these are as follows:

Location (Cost) Free Spins Multiplier Max win
Jungle City (50 x stake) 15 x5 16K x stake
Lake City (100 x stake) 25 x8 30K x stake
Gold City (200 x stake) 50 x15 50K x stake

The RTP increases significantly if you purchase the feature, from 96.5 % to 98 %, so it’s definitely something to consider. Just to be clear, the RTP is the same for all 3 options.

The visual experience will probably make things fall into place for you, and give you a good overview of what to expect.

Review Summary

3 Secret Cities is a very solid treasure hunt slot, and it’s safe to say that this is the best slot 4ThePlayer has released so far. The theme might not look unique at first glance, but the budding developer has made it their own via the engaging visual style and the innovative Bonus Up progression system.

The Bonus Up feature keeps you motivated as you hack your way through the base game grind, and all 3 bonus rounds come with solid potentials. The background shifts as you discover new cities, but not all that much is happening in the base game. This makes the bonus buy very tempting, not least since the RTP increases to 98 %. Overall, a solid production that clearly demonstrates 4ThePlayers ambition and creative talent.


  • Innovative Bonus Up progression
  • 3 unique locations and bonus round tiers
  • Bonus rounds w/ progressive win multiplier
  • Win up to 50,000x your stake
  • Bonus Buy w/ 98 % RTP


  • Base game is very much a grind
  • Bonus Buy not for UK players

If you enjoy 3 Secret Cities slot you should also try:

Gonzo's Quest Megaways - is one to try if you like high risk/reward treasure hunts in the south american jungle. This is NetEnt’s excellent follow-up to their most iconic game, and it comes with a higher win multiplier range, as well as a few brand new features. The bonus round can lead to payouts up to 21,000x your stake.

Lara Croft Temples and Tombs - takes you on another jungle/temple adventure with a powerful female lead, and the rolling reels win multiplier gives you more base game action than in the game at hand. There are also 3 fixed jackpots up for grabs here, as well as a bonus round where you can win up to 7,343x your stake.

Cat Wilde and the Eclipse of the Sun God - is similar to Gonzo’s Quest, but the cascading win multiplier goes as high as 70x in the bonus round. It goes to 10x in the base game, and you can win up to 5,500x your stake at the most.
