KQuity

KQuity powers live win-probability predictions in Hivemind and provides game analysis for Killer Queen — a 10-player arcade strategy game where teams of five race to win by military dominance, economic victory (berries), or snail ride.

Models

Win-probability model

A LightGBM classifier that predicts P(gold wins) from 52 in-game state features (berry counts, snail position, kills, warrior upgrades, etc.) extracted at each game event. A typical game produces 100–300 events, giving a real-time probability curve from start to finish. Trained on quality-filtered game data with symmetry augmentation.

Game quality classifier

Not all recorded games are competitive — many are casual warm-ups, kids mashing buttons, or half-empty cabinets. The quality classifier separates real games from junk using 69 hand-crafted features computed over the full event stream. It achieves an AUC of ~0.908 using logged-in games as positive examples and the unfiltered population as negatives, with tournament games anchoring the decision threshold. Its primary role is curating clean training data for the win-probability model.
