Testing Notes: Here’s What Happened When We Played Chambers of Ancients

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 200 spins on Chambers of Ancients on Play n Go’s test server prior to release to test the game. This is what happened.

  • Stake Size: £
  • Start balance: £25,000
  • End balance: £
  • Hit Rate: 18% (36 winning spins in 200)
  • Biggest Win: 437x
  • Free Spins Round: 2

Chambers of Ancients teased with a low hit rate at just 18%, but it really kicked off in the free spins round on one occasion, notching up a big 437x win that you can see in the screenshot below. The key to that was unlocking bonus games multiple times over because the keys are held rather than re-setting between spins. That makes it easier to collect 3 of any kind and in doing so unlocking a chamber. I was also helped by a re-trigger that meant I started with 8 spins but ended up playing 16 in total.

In short, this is a classic high variance slot. It was very frustrating for most of those 200 spins but once the free spins round got going, it was superb. The round just kept delivering, with 4 or 5 bonus chamber games playing out and it’s easy to see how it could go even futher. On the flipside of course, on a slow day, Chambers of Ancients could be a real grind.

What We Liked

  • FOUR different Hold and Win bonus games
  • Wild Master Keys help to unlock each bonus game chamber
  • Big 20,000x maximum win
  • Free spins re-triggers to give you up to 50 spins
  • Epic artwork and soundtrack

What We Didn't like

  • Low RTP settings at some casinos
  • High volatility can mean the game burns you

Epic Scenes In This Superb Slot With FOUR Different Gods

Chambers of Ancients is a gods-themed game with suitably epic design. The action takes place somewhere in the mountains of the gods with huge rocky cliff faces surrounding the reels and floating islands of rocks drifting amongst the clouds above. There is an ethereal soundtrack that doubles down on the sense of wonder and the reel set itself is stacked with gods from a mixed catalogue of belief systems, including Norse, Hindu and Celtic. At the start of the game, the gods appear from a giant portal center screen, each bringing their own powers. And the narrative is carried through into the bonus games where each god has a chamber in which hold and win games are played. It’s a well-executed idea and for those who enjoy their gods-slots, a nice addition to the category.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Chamber of Ancients has FIVE RTP settings – 96.31%, 94.31%, 91.31%, 87.31% and 84.31%.  Your casino may choose to run the game at any one of these rates. Whilst most UK slot sites will pick one of the higher rates, some may go as low as 87.31% in my experience. If you hit the ‘?’ at the bottom of the game screen the game rules will load up, including the live RTP setting. If it’s lower than 94.31% I would look elsewhere.

I recommend playing at MrQ casino where the RTP rates are consistently at the top end of the scale.

This is also a high variance game so it will be volatile and unpredictable in its pay distribution. That is matched by a very strong max win potential as we are about to find out.

Maximum Win

Our Score 9

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The top payout from Chambers of Ancients is 20,000x. That is at the higher end of Play n Go’s highest max win games though there are much bigger wins available on games like Kiss: Reels of Rock (50,000x) and The Last Sundown (36,000x).

Symbols and Paytable

Our Score 8

Chambers of Ancients plays out on a 5 reel and 3 row game area with just 10 paylines to win on. Wins are triggered in the usual way by landing 3 or more identical symbols across a line from left to right, starting at the left most reel.

The Paytable in Chambers of Ancients
The paytable with 30x for 5 Thor symbols

There are 11 symbols in the paytable. Low value ones are the cards, 10 through to Ace, valued at from 0.5x for 3 10s up to 5x for 5 Aces. The premiums are the 4 gods – Thor, Athena, Ganesha, Caishen, and Eset. These are valued at from 1x for Eset up to 30x for 5 of Thor.

There is a wild too, represented by a star emblem. This will substitute for all other pay symbols to complete paylines. It also comes with its own pay value of 4x, 8x or 40x for 3, 4 or 5 on a line. In addition, Wilds also expand to the full height of their reels if in doing so they can help to complete more paylines.

Features and Gameplay

Our Score 9

In Chambers of Ancients there is a bonus Hold and Win game associated with each god. You have to unlock the games which take place in a Chamber.

Unlocking the Bonus Chamber Games

The games are unlocked by landing keys. Each god has a key associated with them and you need to land 3 of the same type on one spin to unlock the respective chamber. Here, the wild master key, displayed with the wild symbol when it lands, can help you here because it will make up the numbers if you only land 1 or 2 of a bonus key type. But that’s not all, if you land THREE wild master keys, then you get access to ALL four bonus games, one after the other!

How The Bonus Chamber Hold and Win Games Work

So, once you have unlocked any of the bonus games, then you are taken to the god’s chamber. A 3×3 grid is displayed and a Hold and Win game plays out. During the game, cash value coins and special coins land, though some positions will show neither. As long as at least one coin lands on a spin, the counter re-sets. And if the entire grid is filled with coins, all values are collected, the grid is cleared and the spins re-set to 3 to start again.

The cash value coins take their value from the god whose chamber you are in like this:

  • Eset – 2.5x
  • Caishen – 5x
  • Ganesha – 7.5x
  • Athena – 12.5x
  • Thor – 25x

The special coins each activate the following events:

  • Collector Coins – takes the value of all cash value coins on the grid before they are removed
  • Value Booster – adds a random value to one cash value coin on the grid before disappearing
  • Multiplier Coin – doubles the value of all cash value coins on the grid before disappearing
  • Single Multiplier Coin – a 2x, 3x, 4x or 8x multiplier is applied to one coin on the grid
  • Mystery – will reveal a cash value coin or a different special coin from this list
  • Value Coins – show a prize of 0.1x to 5x depending on which bonus game you are playing

The bonus game ends when 3 successive spins return no coins.

Free Spins Round With More Keys

There is also a free spins round in Chambers of Ancients. It is unlocked by landing mask scatter symbols as follows:

  • 3 mask scatters – 8 free spins
  • 4 mask scatters – 10 free spins
  • 5 mask scatters – 12 free spins

During the free spins there are more keys available via wilds and gods, which means a greater chance of triggering the bonus games. It is also possible to re-trigger the free spins to give yourself as many as 50 free spins. 

And, finally, if you get REALLY lucky, you can trigger a bonus game AND free spins on one single spin. In that instance, the bonus game, then the free spins round play out in order.

The Final Verdict

Chambers of Ancients has the making of a classic. The theme and features don’t break new ground but the powerful configuration of those Hold and Win rounds is set to deliver some epic wins in time. You could complain about the low hit rate here but it would be wrong because it’s a natural trade-off being made to allow for the kind of win sequences that every high variance fan craves. And when this game gets going, it really can produce the goods as the short test session showed us. I wouldn’t recommend this slot to anyone but the most dedicated high volatility players, but for that group, this is one of Play n Go’s best releases for some time.

Useful Tips When Playing Chambers of Ancients

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Keep Your Eyes On The Meters Above The Reels

There is a meter for each god displayed above the reels. Each key you collect lights up one position on the meter. Fill 3 for any god and you will unlock their chamber and Hold and Win game. Watch in free spins as they remain lit between spins rather than re-setting for a better chance of triggering.

2. Set Your Stake Low

The test session showed how tricky this game can be. Despite one big win the hit rate was just 18% which means a lot of dead spins which can burn your balance quickly. So choose a low stake to absorb the tough times. You can spin from as little as 10p.

3. Make Sure You Play At A Favourable RTP

Remember, some slot sites will run this game at a low RTP – some at less than 90%. Make sure you check the rate on the game info screen before you start playing to be sure you are not getting short-changed. Look for casinos with the optimum 96.31% rate.
