A Megaquarium 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.

Final prices with fees and discounts applied
Megaquarium for PC starts at €5.60 (€6.43 with fees) at Gameseal, a Steam gift, which is 16% under the €7.64 (no fees) it costs on the official store.
That €5.60 (€6.43 with fees) already includes the SEAL17CKD coupon, so apply it at checkout or the store will show you a higher price.
There is a cheaper listing, €5.02 (€6.19 with fees) at Gamivo, but it is a Europe key and it will not redeem on a US account however good the price looks.
Supply is thin — 8 offers from 6 stores — and thin supply keeps prices steady rather than falling.
It is €0.29 away from its all-time low (€7.35, back in December 2024).
That €7.64 (no fees) key is at one of its best prices.
Worked out from 1,850 daily records of the Steam Key for Megaquarium 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.
By format: Steam Gift from €5.02 (€6.19 with fees), Steam Key from €7.64 (no fees) and GOG Key from €8.99 (€10.06 with fees).
5 of the 8 offers work on US — the Global ones plus the ones issued for your own region.
37 outlets reviewed it and it averages 76 out of 100, with 78% recommending it.
