A The Stone of Madness Steam Key — also known as a CD Key or digital code — is the official activation code you redeem on Steam and keep in your library permanently. From €3.35 (-88%) at Difmark, Steam Account format · Cheapest official key: €5.47, 81% below the €28.99 Steam price · 16 verified stores, 32 offers in stock · Updated 02min ago.
The Stone of Madness for PC starts at €3.35 at Difmark, 88% under the €28.99 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €5.47 at Gamivo.
That €3.35 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
With 32 offers across 16 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 39% under its average of €5.46 since 2025, so today is a better entry point than most days of its life.
That €5.47 key is at its usual price: no bargain, no spike.
Worked out from 1,730 daily records of the Steam Key for The Stone of Madness across 15 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.
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Gamivo costs €2.12 more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
Beyond the standard edition at €5.47, there is the Special at €5.13 at Gamivo, €1.78 more. Check on the store what each one adds before paying the difference.
27 of the 32 offers work on US — the Global ones plus the ones issued for your own region.
35 outlets reviewed it and it averages 72 out of 100, with 69% recommending it.
One listing is worth ignoring: the Steam key that Greenmangaming has at €33.98 is more than 10 times the cheapest offer and is not what this game costs. The number to work from is €5.47 at Gamivo.
