The winners: Winners here lead with Clicker + Idler, priced around $3. The breakout hits carry Minimalist + Pixel Graphics + Relaxing; a typical game here doesn't.

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