It looks like you are the new sheriff, but some bad guys eagerly waiting to shoot you. Agree to a duel to the death at high noon, in true Western tradition to restore the peace in the idyllic town! Despite the heat you must be concentrated, faster and smarter than the bandits. Try to win one Golden Duel after another to gain cool upgrades and beat the high score. Ready for the Golden Duel? Good luck!
