The Mound: Omen of Cthulhu for PC starts at €1.76 at Difmark Digital Keys, a Steam key, which is 94% under the €29.99 it costs on the official store.
That €1.76 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
21 stores carry it, 88 offers in total and 82 available right now; the figure above is the cheapest of the ones you can actually order.
That puts it 84% under its average of €10.79 since 2025, so today is a better entry point than most days of its life.
That €1.76 key is at one of its best prices.
Worked out from 568 daily records of the Steam Key for The Mound: Omen of Cthulhu across 13 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.
The cheapest offer is already a key for your own account: €1.76 at Difmark Digital Keys, so there is no reason to weigh up a shared account here.
The 13 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Beyond the standard edition at €1.76, there is the Deluxe at €18.31 at K4G, €16.55 more. Check on the store what each one adds before paying the difference.
71 of the 88 offers work on US — the Global ones plus the ones issued for your own region.
One listing is worth ignoring: the Steam gift that G2A has at €59.39 is more than 33 times the cheapest offer and is not what this game costs. The number to work from is €1.76 at Difmark Digital Keys.
Get it now: the cheapest key is at Difmark Digital Keys for €1.76 and the game stays on your own account.
The lowest we have ever seen is €2.12, so waiting is unlikely to give you much more than you already have today.
