Tagalon is an action arcade game. The player's task is to find the largest possible number of jewels and a key to the castle. The search takes place around the castle and its courtyard. The seeker encounters on his way other knights, peasants and skeletons. The player can find a variety of items, such as a bomb, shield or extra energy. But the greatest skill is the avoidance of contact with the enemy. The player may carry only one item at the same time. Picking up a new object means loss of the old one.
