What kind of happens on here is that you start up your barn and you purchase your first horse. You then get to board and train your horses to make them the best they can be. There are TONS of breeds to choose from. The more rare a horse is or the better its conformation (its stats for its build) the more expensive the horse generally is. After a horse turns 3 you can enter competitions such as shows and jumpoffs which help you earn money. At three, you can also breed your horses to create new foals for your stable. You can breed from your stock, or pay the stud fee of another members horse. A lot of people try to create the best lines possible for their horses so that the performance increases over generations of horses. I'm returning from a long leave of absence so I still have questions myself, but if you have any questions you can always message me (by clicking on my barn name under my post and then hitting the Send Message tab that is on the top right-hand side of all members' pages).
