Breyer-Opoly is a version of Monopoly published by Late for the Sky, a company that specializes in Monopoly clones. The game features model horses made by Breyer. All the spaces have images of model horses and all the deeds and cards have the names of horse breeds on them.
Players roll dice to determine how far they move. Landing on a space gives the player the option of buying the property. When a player collects all the properties in one color group, the properties can be improved by building. When players land on a space owned by another player they must pay rent. Rent is determined by the location of the property and the number of improvements on the space. Some spaces instruct a player to draw a card which can be beneficial or harmful to the player. Players must avoid going bankrupt to stay in the game. The winner is the last player left in the game.
