Methodology & limitations

Sales estimates use an additive Boxleiter-derived heuristic against public Steam review counts. They are not authoritative sales data, and the fixed display range is not a statistically validated confidence interval. Actual results may fall outside it, especially for deeply discounted or bundle-heavy titles. Algorithm version v1.0. Read the exact method and validation status.

indielist estimates lifetime unit sales for Megaquarium at roughly 146,000 to 341,000 copies, with a median around 244,000, derived from its 3,748 Steam reviews using a multi-factor Boxleiter method (version v1.0). That median maps to approximately $3.5M in net revenue after Steam's 30% cut, regional pricing, and refunds. Unlike black-box trackers, the full calculation is shown on this page: a base review-to-sales multiplier is adjusted for release year, launch price, review sentiment, studio size, and genre, and every adjustment is listed so developers, publishers, and investors can audit exactly how the figure was reached. The range itself reflects genuine uncertainty — review-to-sales ratios vary widely between games — so indielist publishes a low, median, and high band rather than a false-precision single number, and treats free-to-play, heavily discounted, and bundle-distributed titles as having wider error margins still.

On the developer side, Twice Circled's other releases and Twice Circled's wider catalog are one click away, letting developers benchmark where Megaquarium sits among a studio's body of work and how its publisher's portfolio performs. Because indielist maps studios, publishers, games, and funding into one connected graph, the same Megaquarium page serves three audiences at once: players hunting their next Casual game, developers studying how comparable projects were positioned and what they sold, and investors tracing which teams and labels are active in the space. A machine-readable markdown mirror of this page is published at the same path with a .md suffix for AI assistants, and its review, price, and sales-estimate figures are refreshed on a schedule rather than frozen at launch.
