For breeding, either gene may be passed on. Thus a speedy horse may not always pass that speed to its offspring, since it may also carry a slower speed gene. If a horse carries high values in both genes then all its offspring will reflect that. Stress Various activities add stress to a horse, including running a race, stumbling, breeding. Stress increases the chance that a horse will be injured in a race, or die.
Owners can remove horses from races for rest.
Resting horses can later be returned to racing, or converted to breeders. Aging As a horse ages, its chances to win races are reduced. Age also increases the chance of injury and death. You can restart if you own no horses or if your loan exceeds your worth. Players are assigned to factions randomly when they start the game.
