The Bloxism Score
The Bloxism Score is a single 0–100 number that summarizes how a Roblox game is doing right now. It blends four signals we can measure honestly from public data. It is notan official Roblox metric, and it deliberately avoids anything we can't verify (there is no hidden retention or revenue data baked in).
The formula
Each component is normalized to a 0–1 value, multiplied by its weight, and summed. The total is multiplied by 100 and rounded:
score = round(100 × ( 0.4 × popularity + 0.25 × rating + 0.2 × growth + 0.15 × stability ))
The weights sum to 1.00, so a game that maxed out every component would score 100. Current formula version: v1.0.0.
The four components
| Component | Weight | How it's measured |
|---|---|---|
| Popularity | 0.4 | Current concurrent players on a logarithmic scale, mapped so 1,000 players ≈ 0 and 1,000,000 players ≈ 1. Log scale keeps a 500k game from dwarfing everything below it. |
| Rating | 0.25 | The public like/dislike ratio from Roblox's votes API, as a fraction (95% → 0.95). Falls back to a neutral 0.5 when a rating isn't available. |
| Growth | 0.2 | 7-day percentage change in concurrent players, mapped from −25%…+25% onto 0…1. Neutral 0.5 until we have at least seven days of snapshots. |
| Stability | 0.15 | 1 minus the 7-day volatility (coefficient of variation of the player count). Steadier concurrency scores higher. Neutral 0.5 until enough history exists. |
Confidence & honesty
Growth and stability need history to compute. Until we've collected enough snapshots for a game, those inputs use a neutral 0.5 rather than a guessed value, and we label the score's confidence as low or medium (shown with a ~ prefix). We never invent data to fill a gap — a thin-history game simply carries a more cautious score until real numbers arrive.
Why it can change
The score updates every time we take a fresh snapshot, so it moves with a game's real activity. If we revise the formula, we bump the version number above so changes are auditable.
