Greyhound racing is the quiet cousin in the suite. US-based readers often assume the industry is dead — Florida banned it in 2020, only WV has active domestic tracks remaining — but the UK, Ireland, Australia, and New Zealand all have busy, well-regulated meetings most nights of the week. We built Greyhounds against those jurisdictions.
Trap draw × running style
The single most-predictive feature in a greyhound race is the match between the dog’s preferred running style and the trap it was drawn. A classic railer (style R) drawn in T1 with middle-runner rivals inside of it is a live front-runner waiting to steal the race. A wide runner (style W) drawn in T1 is a paper anchor — it’ll cross the entire field at the first turn.
The scanner computes a draw-style matrix per meeting and a 14-day rolling box-bias reading per track. When a hot-box draw matches a clean-trip running-style profile, and the current market is paying a price that over-weights recent bad form, that’s the textbook overlay setup.
Form
Form in greyhound racing reads differently than in horses. Trouble- in-running codes (QAw, SAw, Crd, Ck, Bmp) matter more than finishing position — a dog beaten three lengths after being crowded and checked at bend 1 is often the real winner of that race. The skill doc teaches the scanner to treat form letters plus trouble codes as the real signal.
Sectional times
On short courses (< 400m) the first-bend sectional matters more than the final time. Dogs are ranked by their first-section split against their nightly field; the fastest-at-meeting stat is a high-ROI angle when paired with a good trap.
Free mode is fully featured
Unlike Horses, Greyhounds has a genuinely complete free-mode path. GBGB publishes UK racecards (scrape, cache 15 min min), IGB publishes Irish racecards (same), Betfair Exchange delayed provides odds across all four jurisdictions, and GRV’s Isolynx feed publishes Victorian sectionals in free JSON. Paid mode adds Topaz (AU NSW/QLD/WA/TAS/NT/SA/NZ) for operators who want wider AU coverage.
Staking
Quarter-Kelly, capped at 2% of bankroll per race — tighter than horses because variance in greyhound racing is meaningfully higher. Total meeting exposure is capped at 8% of bankroll; the smallest- edge targets get trimmed first when the cap binds.
