Chambers of Ancients Review: Keys, Wilds and Five Bonus Chambers

Chambers of Ancients at a Glance

Chambers of Ancients turns a mixed-mythology treasure hunt into a system of keys and bonus rooms. Play’n GO uses a five-reel, three-row base game with ten paylines. Matching keys can open a chamber, while Master Keys have a wider role. Free Spins support the same idea by making keys more likely to appear, rather than taking the player into an entirely unrelated feature.

Our Triple Tumblin’ Totems review covers cascade-based bonus tiers. For separate storm, respin and Free Spins features, see Beasts of Fire Inferno.

Features and Gameplay

Keys Give the Symbols Another Role

High-paying symbols connect to particular chambers and the keys that unlock them. Three matching keys start the relevant Hold and Spin bonus. Different keys therefore lead to different chambers, rather than simply contributing to one shared trigger.

Wilds can bring a Master Key. Three Master Keys open every chamber in order of value. This is a separate result from opening one room with three matching ordinary keys. It is the feature that gives the vault theme a practical role in the rules.

Inside a Chamber

The bonus uses its own three-by-three grid with spaces for coins. It starts with three spins, and each new coin resets the counter. When all positions are filled, their values are awarded, the grid clears and the feature starts afresh.

Special coins can collect values, apply multipliers, raise values or reveal a mystery effect. Those effects make the chamber more involved than a grid of fixed coin prizes. Follow the information panel for the exact effects used in the room you enter.

Expanding Wilds and Free Spins

Wilds expand to fill a reel. That expansion does not remove or alter an attached key, so the visual Wild effect and a key-based feature can still occur together. It is useful to treat them as two jobs carried by the same result.

Three or more Scatters start Free Spins. The initial award can reach twelve spins, depending on the number of Scatters. The Hold and Spin chambers remain available during the feature, with an increased chance of keys appearing.

Free Spins are therefore more than a break from the base game. They feed into the chamber system. That connection is the most important rule to understand before comparing this game with a simpler scatter-triggered slot.

Our View of Chambers of Ancients

The game gives collection symbols a clear purpose. Ordinary keys select one bonus room, Master Keys can open a sequence, and Free Spins support those triggers. It rewards learning the symbol roles in a demo before spending money on the base game.

There is also more to follow than in a basic ten-line game. If you prefer a single Wild and a straightforward Free Spins counter, the layered chamber rules may feel busy. The mythology mix is distinctive, but the key system is the real reason to explore it.
