The Genre Heatmap provides a visual breakdown of every Roblox genre’s health — showing demand, crowding, and growth at a glance, plus a plain-English verdict on whether to build there.

​
How It Works

RoLearn uses Roblox’s official genre taxonomy (the new genre_l1 / genre_l2 fields), not the deprecated legacy genre field, so names match what you see on Roblox and games no longer collapse into a single “All” bucket. Every metric is computed from live CCU data and refreshed every 6 hours. Three independent pillars answer “should I build a game in this genre?”:
  • Demand — total concurrent players across the genre (the size of the audience).
  • Saturation (crowding) — R / (R + demand_per_game), where demand_per_game is the genre’s CCU spread across its active games (CCU ≥ 10) and R is the platform-wide norm. 0.5 means the genre matches the platform average; above 0.5 is more crowded, below is roomier. This is a supply-vs-demand measure, not a raw game count.
  • Growth — the change in genre CCU versus a fixed baseline 7 days ago.
Two supporting signals refine the picture:
  • Concentration (top3_share) — what fraction of players the 3 biggest games hold.
  • Openness (newcomer_share) — of the top-20 games’ players, the share held by games launched in the last 12 months. Low openness means a frozen leaderboard owned by old incumbents (hard to break into).

​
Reading the Heatmap

The heatmap plots saturation on the x-axis (divider at 0.6) against growth on the y-axis, with bubble size = demand. As a quick scale for saturation:
SaturationMeaning
< 0.45Open — room to enter
~0.50Platform norm
≥ 0.60Concentrated / crowded
Each genre also gets an entry verdict — the plain-English answer:
  • strong — healthy demand, room to grow.
  • enter_with_edge — viable, but you need a differentiator.
  • avoid — a frozen top (incumbents own it) or crowded and declining.
  • unproven — too little demand to judge yet.
An opportunity score (0–100) combines demand percentile (0.40), growth (0.35), and openness (0.25), and is always shown alongside its sub-scores so the number is auditable.
“Trend tags” like Brainrot, Skibidi, or Anime are not genres — they are cultural tags matched separately by keyword. Don’t confuse a hot trend tag with an official genre’s saturation.
Combine the Genre Heatmap with Launch Timing to find the right genre AND the right time to release.

Frequently Asked Questions

Saturation measures supply versus demand: how thinly a genre’s players are spread across its active games, relative to the platform norm. RoLearn scores it as R / (R + demand_per_game) — 0.5 is the platform average, and 0.6+ is crowded. It is not just a game count, so a genre with many tiny games can still read as open if the audience is large.
It changes regularly as the market shifts. The Genre Heatmap updates automatically to reflect current conditions — check it before starting a new project to see where blue ocean opportunities exist right now.
The Genre Opportunity Engine weighs multiple market factors including player demand, growth momentum, and competition density to produce a composite score. Higher scores indicate stronger opportunities for new games.
