Under the hood

Ratings & Simulation

How four on-chain stats become a full basketball engine — the BBL conversion, physical ratings, composite archetypes, and the team synergy that wins playoff series.

How games are simulated

Your four core stats don't go straight onto the court. The BBL engine first expands them into a deeper set of in-game skills, layers in physical ratings from your position and Sneaker, then simulates each possession to produce a box score. Understanding the expansion is what lets you build a roster that punches above its Overall.

BBL conversion (4 → 10)

Each of the ten in-game skills is a weighted blend of your four core stats (Dunk, Playmaking, Shooting, Defense). This is the exact mapping the engine uses:

In-game skillBlended from
Inside90% Dunk + 10% Shooting
Dunks / Layups100% Dunk
Free Throws100% Shooting
Mid Range100% Shooting
Three Pointers100% Shooting
Offensive IQ20% Dunk + 50% Playmaking + 30% Shooting
Defensive IQ100% Defense
Dribbling100% Playmaking
Passing75% Playmaking + 25% Defense
Rebounding50% Dunk + 50% Defense
Notice Passing pulls 25% from Defense and Rebounding is half Dunk, half Defense — so a high-Defense Baller quietly helps your ball movement and the glass, not just your stops.

Physical ratings

Height, Strength, Speed, and Endurance aren't on-chain — they come from your Baller's assigned position and build. Position is inferred from your strongest core stat (Playmaking → PG, Shooting → SG, Defense → SF, Dunk → C), and each position has three build styles with different physical baselines. Jumping comes entirely from your equipped Sneaker — see Sneakerz.

Composite tags

From the in-game skills the engine derives eight composite tags— archetypes that describe what a Baller actually does well. A Baller "earns" a tag at a rating of 75 or higher:

TagWhat it measures
Three-Point ShooterSpacing and outside scoring.
AthleteStrength, height, speed, and hops combined.
Ball HandlerDribbling and speed off the bounce.
Interior DefenderRim protection — size, strength, def IQ.
Perimeter DefenderContaining guards — speed and def IQ.
Post ScorerScoring with size and inside touch.
PasserCreating for others — passing and IQ.
RebounderHeight, rebounding, and motor.
Below 75 a rating still pulls its weight — it keeps contributing to team synergyas long as it's 60 or higher.

Team synergy

Synergy is a team-wide bonus determined by how well your five starters' composite tags complement each other — and it recalculates on every substitution. It has three boosts and one penalty:

  • Offensive synergy — from shooting, ball-handling, passing, post scoring, and athleticism across your starters.
  • Defensive synergy — from interior defense, perimeter defense, and athleticism.
  • Rebounding synergy— from your starters' rebounding.
  • Perimeter penalty — a team thin on perimeter skill (three-point, dribbling, passing across your PG/SG/SF) gets its offense docked until it has enough perimeter punch.
How the perimeter penalty works

The sim checks the combined perimeter synergy at your guard and wing spots. If your backcourt and small forward can't shoot, handle, or pass enough collectively, your offensive synergy is scaled down. The fix isn't one superstar — it's making sure the players who handle the ball on the perimeter can actually play on the perimeter.

Alpha mechanic

Composite tags and synergy are tuned for balance and the exact thresholds can change between seasons. Treat the shapes above as the model; check the Discord for the current season's numbers.

Synergy in the playoffs

In the regular season synergy is a meaningful boost. In the playoffs it's worth about 2.5× as much — between two evenly matched rosters, the better-built, better-balanced team usually takes the series. Build for synergy, not just five high Overalls.
