Horse racing is a fairly closed universe but nevertheless fascinating. We bet on the horse that will win the competition and exceed all others, accompanied by his jockey. It is the latter which reassures the horse and give instructions during the race, with his whip.
The balance of the jockey is very important, especially when it has to go through obstacles with his horse.
Horse race games will ask you to move your horse and make it docile enough for it to be able to win all the races and bring enough money to the rider.
