Games like Mind Spheres

A typical game among these

≈ 326–6k copies

≈ $320–$20k after Steam's cut

from ~22 reviews

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

1 of the 8 similar games is a hit.

Best case: Portal at ≈ 12.6M–20.5M copies, ≈ $34.6M–$93.1M after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 8 reviews in their first month; the range was 3 to 154.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Puzzle (8 of 8) and Sports (7 of 8).
The winners: Winners here lead with Puzzle + Puzzle-Platformer, priced around $10. The breakout hits carry Puzzle-Platformer + 3D Platformer + Singleplayer; a typical game here doesn't.
When they shipped: The similar games span 2007 to 2025, and 3 of the 8 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).
