In Tower Master you race your opponents to the top of a boobytrapped tower with the goal of saving the princess. The catch is that each floor is designed by one of the players. Before starting a game, players build a floor using the extensive drag-and-drop level editor. At the start of a match, each player picks one of their selfmade levels to bring into battle. When the race begins, all players make their way to the finish of each level, trying to survive all the boobytraps layed by their opponents. After all levels are completed, the victor is the player who reached the top of the tower the quickest (and died the fewest).
