How many copies did Gem Blast sell?

Q: How many copies did Gem Blast sell?

99 to 161 copies, based on its 4 Steam reviews. This is a labeled estimate from the review count, not exact sales.

Estimated copies sold: ≈ 99–161; $218–$585 after Steam's cut $396–$900 before Steam's cut; from 4 reviews (4 user reviews); Only 4 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.

Games like Gem Blast

A typical game among these

≈ 545–454k copies

≈ $2k–$2.3M after Steam's cut

from ~5k reviews

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

4 of the 8 similar games are hits.

The genre you'd be entering

These games: The similar games share Rogue-lite (7 of 8) and Puzzle (5 of 8).
The winners: Winners here lead with Card Battler + Card Game, priced around $20.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2023. 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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
