- Elo-derived game-winner estimate
- Elo-derived game-winner estimate: CHI 17% · BOS 83% Model Performance: the Elo rating’s game-outcome accuracy is not yet established — 71 regular-season games graded so far; the preregistration requires 300 before any accuracy claim. An estimate derived from the Elo team rating — not an independently validated probability, not a simulation result, and not a betting recommendation.
- Projected score
- Not published. The Official Forecast does not include NBA team scores, so no projected score is shown.
- Withheld
- Team scores, margin and total, player ranges, prices · Not shown: this model's team score is a sum of player simulations that ignores the opponent, can contradict the Elo side, and has not met its historical checks.

Medians from the frozen player simulation; MIN is expected minutes. PRA, P+R and P+A are medians of the per-draw sums over the same simulated draws, so they are not the sum of the medians beside them. Each figure is that player's own median, published as is. Player medians are not adjusted to add up to a team score. “—” means the figure was not published for that player. Not betting recommendations.
Model vs. sportsbook line · NBA player props
83 of 154 projections have a qualified sportsbook line. Direction not shown: 10.
This game: 73 lines · ▲ 21 ▼ 52 · View lines →
- OVER means our model's projection is above the sportsbook's line.
- UNDER means our model's projection is below the sportsbook's line.
- NEUTRAL means our model's projection is the same as the sportsbook's line.
- Difference is our projection minus the line: 36.0 against 29.5 is +6.5. A gap smaller than 0.05 shows as +0.0 or −0.0 and keeps its direction.
- A line older than 6 hours, taken after the game started, not matched to the player and game, suspended, or for a statistic we do not project is shown with the reason and is not compared.
- Over and Under prices are the sportsbook's American odds. A dash means the sportsbook did not post that price; it is never a zero.
- Comparison not shown means the model and the sportsbook line are both shown without a direction, because that statistic's forecast has not yet met our calibration standard.
- It is a comparison, not a bet recommendation or a probability, and it guarantees nothing.
Sportsbook availability varies by state.

Simulation outcome · this run
Simulated scenario (hypothetical) · central · run 566 · the stored run nearest the middle of this engine's own simulated games. It is chosen without looking at the Official Forecast, so either side may win it; it is one simulated game, not the Official Forecast, and changes none of its numbers
Chosen by rule, not by hand: the stored run nearest the middle of this engine's own simulated games: of the runs that ended in regulation, the final closest to the pool's median home and median away points (in pool standard deviations); ties → lowest run number. The Official Forecast is not consulted, so either side may win it.
In this engine's 1,000 simulated games, BOS won 77.0% and CHI 23.0% (the engine's own share, not the Official Forecast).

About this simulation
Game Simulation engine: NBA possession engine (nba-possession-sim-v0) — not the Official Forecast, not the NBA v1 Challenger (evaluation only)
- This Game Simulation is generated by the NBA possession engine (nba-possession-sim-v0) from the same frozen inputs as the Official Forecast.
- It is not the Official Forecast.
- Each run is a hypothetical game — one possible outcome, not a prediction and not a guarantee.
- A different simulated score does not change the Official Forecast.
Technically verified
Every run on this page passed the engine's consistency checks when it was generated and again when this page was built: game clock, possessions, five players on court per side, scoring, minutes, fouls, and an event log that adds up exactly to the box score. The run you are watching is also re-added from its own event log in your browser (Reconciliation, above).
- Checks
- P1–P11 (clock, possession, five on court, scoring, minutes, fouls, log = box score)
- Seed pool
- 1,000 seeded runs, 1,000 checked, 0 invariant violations
Model Performance — not yet measured
The engine has not been measured against actual NBA results: it has no preregistered evaluation, and it has not been shown to be more accurate than the Official Forecast or the NBA v1 Challenger (evaluation only). Its runs are independent draws (not reconciled to v1's draws). Each run is a possible game, not a prediction and not a guarantee, and nothing it shows changes an official number.
What is modelled: every play, score change, clock reading, possession arrow and lineup on this page comes from one stored event log of the engine, and the box score is that log added up. The court graphic is decorative: player positions, ball movement and shot locations are not modelled.
- Inputs as of
- 2026-10-30 15:50 UTC (the Official Forecast's freeze for this game: the simulation has no later information than the Official Forecast had)
How the runs on this page were chosen
- pool
- runIndex 0 … poolSize − 1 of the engine's fixed seed policy (seed = hash(providerEventId); draw i uses mulberry32(fnv1a32(seed + ':' + i)))
- distance
- official-representative@2 distance to the official v0.1 player expectations (team terms withheld for NBA)
- default
- smallest distance among runs won by the official Elo favoured side; ties → lowest runIndex
- upset
- smallest distance among runs won by the side the official forecast does not favour; ties → lowest runIndex
- high
- total closest to the pool's p90 total (nearest rank); ties → smaller distance → lowest runIndex
- low
- total closest to the pool's p10 total (nearest rank); ties → smaller distance → lowest runIndex
- overtime
- smallest distance among overtime runs; ties → lowest runIndex (only when the pool has one)
- order
- default, upset, high, low, overtime — each pick excludes the runs already picked
Not modelled
- Shot locations, player movement and ball movement (the court graphic is decorative)
- Timeouts and coach's challenges
- Offensive fouls (booked as turnovers; every personal foul is on the defence)
- Bonus / penalty situations (folded into the fitted free-throw trip rate)
- Late-game strategy beyond intentional fouling (overtime is rarer than in real games)
- Technical fouls (folded into odd free-throw trips)
- Fatigue and blowout rest
