Parthenon Quest for Immortality slot review (Netent)

I love these type of slots, as it gives some perspective. Besides, you always learn something new or at least remember your history classes. The slot is interesting. The gameplay has some surprising features, and the animations are excellent. The downside is probably the mathematical model. It can take ages to win the free spins, as the wins in the main game can be pretty substantial!

Parthenon Quest for Immortality – Beautiful slot if you love Ancient Greek slots

Parthenon Quest for Immortality is Netent’s 5th 2021 slot, and it’s an ancient Greek-themed slot. It looks like Netent likes to open the history books, as their 2nd 2021 slot (Rome: The Golden Age) was Roman-themed.

A missed opportunity.

SLOT: Parthenon Quest for Immortality | SOFTWARE: NETENT

Number of paylines: 10,000 ways to win

RTP and variance: 96.03%, High variance

Maximum win: Unknown

Betting range: $€0.20 – $€200

Bonus features: Free Spins

Casino Hipster verdict: Hot, but not HOT! Graphically outstanding, but mathematically it’s flawed.

Gameplay and Features

Parthenon Quest for Immortality has 6 reels of 4 symbols each, and above the middle 4 reels, you have a top row of 4 symbols. In total, you have 10000 bet ways (4x5x5x5x5x4=10000).

The game relies on the avalanche (cascading) mechanic. If you get a win, you’ll get a free re-spin. Afterwards, you see that the winning symbols disappear and make way for new symbols.

The highs are typical Greek symbols. We have the vicious Medusa as the highest paying one. A six-of-a-kind of Medusas yields a 40x win.

The medium paying ones are an ancient Greek Ship, the mythical winged divine horse Pegasus, a Snake and a three-pronged Spear, and these are followed by the A, K, Q, J and 10 as the low-paying symbols.

Then we also have the Wild symbols and the Free Spins symbols.

Wild Generation Zone Feature

The top row of 4 symbols is also the Wild Generation Zone.

Any winning symbols in the Wild Generation Zone transform into a Wild symbol for the next re-spin.

It acts like a roller coaster, as Wilds increase the chances of another win with the re-spin. Don’t be surprised to see five or even ten consecutive re-spins, thanks to this feature.

How do you win the free spins?

It sounds simple, but it isn’t.

You need 3 Free Spins symbols to trigger 8 free spins. Each additional free spin symbol yields another 4 free spins. It can take some while!

You trigger another 2 free spins for each additional Free Spin symbol you may get during the free spins. 

Free spins – increasing multiplier

The free spins play the same way as the main game, but there is one crucial difference.

All wins multiply with a total multiplier, starting at x1, but it can expand to x20.

Each time you manage to transform a regular symbol into a Wild symbol, it increases the total multiplier by +1.

Parthenon Quest for Immortality slot: the payout rate (RTP) is 96.03%.

The RTP of Parthenon Quest for Immortality is 96.03%, which is in line with the RTP’s of Netent slots since mid-2020.

No, Netent has decided to lower the RTP’s and the times that these were well above 96,5% have gone.

Parthenon Quest for Immortality slot: the variance (volatility) is high

According to Netent, we’re talking about a high variance slot.

The maximum win is unknown, but given the multiplier and the 10000 ways to win, I would expect that wins of thousands of times the bet are possible if you’re (very) fortunate.

Pros en Cons


  • Beautiful animations and theme
  • Exciting gameplay, without being overly complicated


  •  From Netent, you expect better RTP-slots
  •   The mathematical model is not correctly calibrated. You get too many wins in the base game, and the result is that it’s too difficult to land the free spins, which is where you would like to be!
