Buy Castle Story Steam Key

Q: Why is the Steam Key of Castle Story safer than the account format?

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 Castle Story to your game library. The account format requires more complicated steps and is more prone to errors during activation.

How much does Castle Story for PC cost right now?

Castle Story for PC starts at €9.10 at Gamivo, a Steam key, which is 7% under the €9.75 it costs on the official store.

That €9.10 already includes the GCDKGamivo coupon, so apply it at checkout or the store will show you a higher price.

There is a cheaper listing, €8.98 at HRKGame, but it is out of stock and issued for Europe on top of that. The cheapest you can buy for US is €9.10 at Gamivo.

Only 10 offers across 5 stores carry it, and thin supply means the price barely moves.

That puts it 7% under its average of €9.75 since 2018, so today is a better entry point than most days of its life.

That €9.10 key is at its usual price: no bargain, no spike.

Those €9.10 are 34% 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, 504 days out of the 1,673 days on record were this cheap or cheaper; the lowest it has ever cost is €2.43.

Worked out from 2,180 daily records of the Steam Key for Castle Story 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 Castle Story in US?

7 of the 10 offers work on US — the Global ones plus the ones issued for your own region.

Castle Story is a strategy game in which we will be put in charge of a hard-working race of beings called Bricktrons. And in the purest Lemmings style, we can have these beings perform all kinds of tasks for our benefit, from digging and gathering resources, to sending them to war and making them explode.

Thanks to the work of our Bricktrons army, we will be able to build any structure, from huge castles to large villages. We will also be able to assemble and create an army of our lackeys, and even build siege weapons as catapults to combat the threats looming over this world. But above all, we will be able to live a unique multiplayer experience, playing with friends and challenging them, conquering their castles and villages and making us with their armies.

We'll also have an editor to create our own worlds and share them with the community, so the gaming experience is greatly enhanced.
