How much does Euclidean for PC cost right now?

Euclidean for PC starts at €0.90 (€1.30 with fees) at HRKGame, a Steam key, which is 74% under the €4.99 (no fees) it costs on the official store.

That €0.90 (€1.30 with fees) already includes the Gocdkeys12 coupon, so apply it at checkout or the store will show you a higher price.

Only 6 offers across 5 stores carry it, and thin supply means the price barely moves.

Is it worth buying the Steam Key for Euclidean now or waiting?

That €0.90 (€1.30 with fees) key is at one of its best prices.

  • Those €0.90 (€1.30 with fees) are 39% below what it usually costs, measured on the store price.
  • Only 5 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, the lowest we have recorded for the Steam Key across 342 days is €1.05 — and today it is below that.
At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 833 daily records of the Steam Key for Euclidean across 7 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate Euclidean in US?

5 of the 6 offers work on US — the Global ones plus the ones issued for your own region.

Attention: This version of Euclidean is for PC and in digital version. The digital versions of the PC games are in the form of a key or cd key, which must be entered into a Steam account to proceed with the download of the game. Some shops may have the "Steam Gift" label which means that an activation link will be sent instead of a cd key.


Euclidian is a geometric horror game, created to be enjoyed with virtual reality devices, set in a universe that leads humans into an endless fall through darkness, madness, futility and despair, in a parallel and distant universe in which no human can survive. We find ourselves in a timeless dimension of space, a place that humanity should never know. 


The game presents us with an endless fall through tense environments belonging to timeless and adverse worlds and universes, consisting of three levels of difficulty: HARD, NIGHTMARISH and IMPOSSIBLE. Each of these difficulty levels is represented by 9 different stages of terror.


Don't forget to check the Steam device for compatible virtual reality devices.

Most common FAQs when buying Euclidean for PC in digital format:

It is a key that will allow you to download the game Euclidean on your PC from official download platforms.
As of 27/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Euclidean on PC is €0.90 (€1.30 with fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Euclidean to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Euclidean, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
