Use the deck of cards in your hands, build a tower and fill it with rooms to produce tools, weapons and magic. Defend from coming enemies and find multiple ways to solve challenges. Find treasure or kill the boss or survive enemy waves to win.

There are six types of cards and even more cards themselves, but not all of them are necessary to complete the levels. Properly cleaned cards will help you solve problems that arise and build a reliable tower.

Levels are grouped into worlds with features and specific enemies with unique decks and game mechanics. Meet the goblin warlord on a mechanical robot, the huge wolf who swallowed the Sun and many other strange enemies.
