Abstract: A method of generating a graphical user interface for horse race betting includes displaying a first list of horses scheduled to run a first race from among a plurality of horses, displaying, in association with each horse of the first list of horses, a win selection element by which a user of the graphical user interface may mark the horse as selected to win the first race, displaying an automatic ticket generation button by which a user may request an automatic selection of horses, and, in response to a user interaction with the automatic ticket generation button, marking one or more horses of the first list of horses as selected to win the first race based on predicted win percentages of the horses of the first list. The method may include displaying, in association with each horse of the first list of horses, the predicted win percentage of the horse.
