How many copies did Stonerill sell?

Estimated copies sold
≈ 174–282
$10k–$26k after Steam's cut $17k–$39k before Steam's cut
from 7 reviews (7 user reviews)
Only 7 reviews so far, so that range swings on one or two people. Read it as a hint, not a measurement.

Copies are estimated from the public review count, adjusted for release year, and cross-checked against SteamSpy's own estimate.

Did the prediction match what actually happened?

We hid Stonerill and predicted how it would do from its 8 similar games. Every figure here, including Stonerill's, is estimated from Steam reviews.

Copies, estimated from reviews

Games like Stonerill

A typical game among these

≈ 28k–1.0M copies

≈ $138k–$12.5M after Steam's cut

from ~14k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

6 of the 8 similar games are hits.

Best case: Against the Storm at ≈ 934k–1.5M copies, ≈ $7.7M–$20.7M after Steam's cut.

The winners
Winners here lead with City Builder + Simulation, priced around $30.
When they shipped
Only 1 of the 8 similar games shipped in the last two years. That says more about which games were found than about the market.
How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
