Horse Breeder Game
Breed horses like a geneticist.
A hyper-realistic equine simulation built with genuine horsemanship at its core. Breed horses using authentic coat-colour genetics across 21 real equine loci, the same genes a 2024 lab can sequence. Manage horses across UK-style livery yards, navigate real-world veterinary conditions, and develop the slow, earned trust between horse and human that defines great horsemanship. Co-developed with an independent developer.
Game Features
Real Coat Genetics
21 equine loci modelled exactly as a 2024 geneticist would describe them: Extension, Agouti, Cream, Dun, Silver, Gray, and the full white-pattern series including Frame Overo with its lethal homozygote. Punnett squares actually predict the foal.
UK Livery Yards
Six handcrafted yards from a Cotswolds family stable to a Perthshire premium sport-horse establishment. Choose DIY, Part, or Full livery per horse, billed weekly the way real yards do it.
Veterinary Realism
Eight conditions (laminitis, colic, mud fever, strangles, sweet itch, equine flu, tetanus, lameness) each with the correct triggers and breed susceptibilities. A Gypsy Cob is three times more laminitis-prone than a Thoroughbred.
Four Seasons
Spring grass spikes laminitis 2.5×; winter doubles mud fever and brings biting cold that punishes under-rugged horses. The same seasonal rhythm a real UK yard runs on, shaping every management decision you make.
Daily Weather & Forecast
Ten weather conditions (sunny, hot, rain, heavy rain, fog, frost, snow, thunderstorm and more) drawn from seasonal probability tables. Each shifts temperature and disease risk: heavy rain doubles mud fever, snow piles on lameness, rain knocks midges down so sweet itch eases. A 3-day forecast lets you plan the week's rugging.
Personality: Nature & Nurture
Every horse carries three personality traits (temperament, boldness, trainability) set at birth from sire and dam, pulled toward the breed's nature, and shaped by your handling. A Thoroughbred runs sharper than a Shire. Strong bonds make horses more willing; show-ring success builds boldness; untreated illness leaves a wary mark. Each trait quietly tilts training rate, bond decay, show presence, and weather tolerance.
Castration & Gelding
Stallions carry hot-blooded biology: slower to bond, harder to train, more reactive in the ring. Gelding is a real horseman's decision: a £180 vet procedure with a 14-day recovery, a small complication risk, and a chance (not a guarantee) of a calmer, more willing horse afterwards. Castration before the growth plates close lengthens the horse a touch too. Permanent, irreversible, and weighed against losing the bloodline.
Rugs, Clips & Comfort
Five rug types (fly, lightweight, medium, heavy, stable) and four clips (trace, blanket, hunter, full) with realistic 60-day coat regrowth. Comfort is a live warmth balance: natural coat plus rug versus today's temperature. A horse left under-rugged in a hard frost will lose health every turn. Buy your tack from the in-game Tack Shop.
Bonding Before Skill
Trust is a real stat. A horse with low bond won't engage with training. Every great horseman from Xenophon to Ray Hunt would tell you the same. Hand-walk, groom, desensitise, then ride.
Shows & Competition
Fourteen breed shows across four seasons, with in-hand, ridden, foal, and breed-specific classes. Score combines conformation, training, bond, and breed fit the way a real judge weighs them up. Prize money, prestige tiers, full per-horse show records.
Conformation Scoring
Twelve polygenic traits (head, neck, shoulder, back, loin, hindquarter, legs, feet, bone, and movement) each inherited via the breeder's equation. Breed the best to the best and watch traits improve across generations.
Turn-Based Pacing
Each turn advances the game by one full day. Seasons change, horses age, care windows tick, and show schedules roll forward. A finite turn budget regenerates over real-world time, so you burn through twenty game-days in a sitting and come back later with a fresh stack. No grinding, no FOMO.
Passports & Papers
Issue a UK-style equine passport with a locked registered name, track pedigree, and manage barn name vs registered name across every yard. The same paperwork system a real horse owner deals with.
Career & Finances
Six equine occupations from Stable Hand to Freelance Farrier, each with per-job XP and daily wages. A full ledger of every transaction (wages in, vet bills out) so you can see exactly where your money goes.
Educational at Every Step
Every term has an info panel explaining what it is, why it matters, and its history. From the General Stud Book of 1791 to the Strangvac vaccine in 2021, the game teaches as you play.
Nineteen Breeds
From the Dartmoor moorland pony to the Newmarket-bred Thoroughbred. The full British Native pony spread, the great heavies, carriage breeds, and hot-bloods. Each with its own coat-colour pool, breed-typical height, and disease susceptibility.
