The main tasks in One Deck Dungeon involve immersion in dungeon exploration. You will have to fight a variety of monsters that will attack the active hero at every turn. Confrontations will involve card duels. You will need to collect a deck of cards to deal a greater blow to your opponents. The course of battles is also affected by chance, when players will be able to throw dice. You can control several main characters at once, alternating between them. For successfully completing stages, you can unlock new characters. The gamer will be able to face a number of challenges that will be held in various locations. In the Dragon's cave there will be a powerful wyvern, which is ready to tear anyone apart. It has additional protection thanks to its thick skin.
