Games like Stack Masters

A typical game among these

≈ 641k–1.2M copies

≈ $3.1M–$7.7M after Steam's cut

from ~17k reviews

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

All 8 of the similar games are hits.

Best case: Human Fall Flat at ≈ 9.5M–15.4M copies, ≈ $52.0M–$139.7M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Physics (8 of 8) and Sandbox (6 of 8).
The winners: Winners here lead with Co-op + Puzzle, priced around $20. The breakout hits carry Co-op + Puzzle-Platformer + Multiplayer; a typical game here doesn't.
When they shipped: The similar games span 2013 to 2022, and none of them shipped in the last two years.

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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
