How much does Fantasy Idle Dungeon for PC cost right now?

Fantasy Idle Dungeon for PC starts at €3.48 (€3.86 with fees) at Key4Games, a Steam key.

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

That puts it 27% under its €4.79 average of the last 7 months, so today is a better entry point than most.

Is it worth buying the Steam Key for Fantasy Idle Dungeon now or waiting?

That €3.48 (€3.86 with fees) key is at one of its best prices.

  • Those €3.48 (€3.86 with fees) are 21% 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, only 8 days out of the 159 days on record were this cheap or cheaper; the lowest it has ever cost is €3.31.
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 495 daily records of the Steam Key for Fantasy Idle Dungeon across 5 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.

Are these stores safe to buy Fantasy Idle Dungeon from?

Worth knowing before you click: Key4Games is cheapest at €3.48 (€3.86 with fees) but has only 37 Trustpilot reviews behind it. If that thin track record bothers you, Gameseal has the same Steam key at €3.40 (€4.06 with fees) with 16.3k reviews and a 4.3 out of 5.

Can you activate Fantasy Idle Dungeon in US?

All 5 offers are Global, so the code redeems on any account no matter where it was created.

Most common FAQs when buying Fantasy Idle Dungeon for PC in digital format:

It is a key that will allow you to download the game Fantasy Idle Dungeon on your PC from official download platforms.
As of 24/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Fantasy Idle Dungeon on PC is €3.48 (€3.86 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 Fantasy Idle Dungeon 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 Fantasy Idle Dungeon, 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.
