The best-supported answer is Adopt Me! : a 2021 Roblox revenue video citing top-earning Roblox games says it earned 22.21 billion Robux , more than any other game on that list. A more recent 2025 earnings roundup instead puts Brookhaven at the top with 2.4B+ Robux , which suggests the answer changes depending on the year and dataset used.

Why the answer varies

Roblox earnings rankings are not a single official all-time leaderboard, so different sources measure different things. Some look at a specific year, while others estimate cumulative Robux revenue over time.

Best practical answer

  • All-time / historical headline: Adopt Me!.
  • Recent 2025 ranking: Brookhaven.

TL;DR

If you mean the game that has made the most Robux overall, Adopt Me! is the strongest answer from the sources I found. If you mean the current top earner in a recent ranking, Brookhaven is listed first.
