155th Anniversary of the Pony Express

155th Anniversary of the Pony Express is celebration of the American mail delivery service that operated from 1860 to 1861. In the game, players control a rider on horseback as they travel from California to Missouri, collecting letters. There are three legs of the journey with a total of 100 letters to grab. The horse will move forward on its own, but the player can control its path with the arrow keys. If they collide with an obstacle, like a rock or tree, or get caught by a bandit or snowfall, the rider will lose some letters.
