3 Secret Cities (Relax Gaming) – Review & Demo Play

3 Secret Cities Slot Overview

When I first fired up 3 Secret Cities, I expected another dime-a-dozen mesoamerican jungle run. It surprised me. The Bonus Up mechanic ties the journey to a map of Jungle City, Lake City and Gold City, and the cartoonish animated backdrops with a subtle jungle soundtrack set the tone. You grind the base game across 1024 ways, but the progression keeps you engaged. I found myself rooting to reach the top tier Golden City before the feature landed, though decent wins can land from all three levels.

3 Secret Cities Slot Information

3 Secret Cities runs on 5 reels, 4 rows and 1024 ways to win. Stakes range from 0.10 to 20 per spin. The RTP sits at 96.5% in standard play, rising to 98.0% when the feature is bought. Variance is high, with a hit frequency of 20%, so patience helps between bursts. The headline potential is 50,000x the bet, which fits the treasure hunt theme. On mobile, the Big Reel Portrait Mode gives two layouts, so the interface stays tidy without losing the animated jungle feel.

The lower paying set is 10, J, Q, K and A, styled with Aztec touches. Premiums are a gold snake ring, a necklace, a jaguar, the adventurer and the priestess. Both character symbols are 1x4 and can cover a whole reel for chunky ways. The Aztec Calendar Wheel is the wild symbol and substitutes for pay symbols. Scatters are the three temple icons tied to Jungle City, Lake City and Gold City. Wins hit on adjacent reels from the leftmost.

3 Secret Cities Slot Features

Everything revolves around Bonus Up. Land two scatters on reels 1 to 3 and you pick one for an instant cash prize up to 50x or a step forward on the map. Land three scatters on reels 1, 3 and 5 to trigger the Bonus Round and a Temple Pick that sets free spins, a starting win multiplier and a super stacked symbol. During the bonus, two scatters add 5 to 10 extra spins. After any feature, you return to Jungle City.

Wild Symbol in 3 Secret Cities

In 3 Secret Cities the Aztec Calendar Wheel acts as wild. It substitutes for standard pay symbols and helps complete ways wins across the 1024 lines. It does not replace the temple scatters, so it cannot trigger the feature on its own. In my sessions it often paired with the tall adventurer or priestess to stretch hits across four rows. That keeps the base game ticking while you grind towards stronger Bonus Up positions on the map.

Bonus in 3 Secret Cities

Two scatters on reels 1 to 3 trigger a pick. You choose one symbol and either pocket an instant prize up to 50x stake or move one step to the next location. The map shows Jungle City, Lake City and Gold City, and the current level is displayed above the reels. This progression is the heart of Bonus Up. It gives a sense of journey between base game spins and sets better free spins packages when the main feature lands with three scatters on 1, 3 and 5.

Temple Pick defines the round. In Jungle City you can get 12 to 15 free spins, a x4 to x5 start and a solid 15,000x to 16,000x cap. Lake City lifts it to 17 to 25 spins, x6 to x8 and 20,000x to 30,000x. Gold City is the top tier with 30 to 50 spins, x9 to x15 and up to 50,000x. During free spins, two scatters add 5 to 10 more. After any bonus, the map resets to Jungle City.

Bonus Buy in 3 Secret Cities

Depending on jurisdiction, a Bonus Buy is offered, though not for UK players. There are three choices tied to the cities. Jungle City costs 50x stake and gives a 15 spin setup with a x5 start and a 16,000x ceiling. Lake City costs 100x and gives 25 spins at x8 with 30,000x potential. Gold City costs 200x and grants 50 spins at x15, with the full 50,000x on the table. The math mirrors a triggered bonus at those tiers.

The RTP climbs from 96.5% in standard play to 98.0% when you buy any of the three. That is a noticeable lift over long sessions. The feature still uses the same super stacked symbol and the same win ways logic. You can also retrigger within the bought round by landing two scatters, which add 5 to 10 extra spins per pick. There is no hard upper limit on total spins, so extended runs do happen at times.

Where Bonus Buy is disabled, Bonus Up progression keeps the journey lively. The background art shifts as you reach new cities and the panel shows the current level. I had sessions where it felt like a grind, then a two scatter pick pinged the map forward and the next trigger hit at a stronger tier. Either route can land serious wins, but the top end really opens in Gold City with that x15 start.
