At the beginning of the game the player has to pick a character, each character has very different characteristics, with their own character skills, exclusive card types and so on. 

The goal of the game is to explore the tower from the bottom up, and there are several large floors, each with a number of branching tree routes, which may lead to various events, such as fighting monsters, resting at campfires, trading with merchants, random events, etc. At the end of each floor, a leader will appear, and after winning the battle, you can move to the next floor.

The game's battle system is turn-based. Each turn the player draws a fixed number of cards from his hand and receives a fixed amount of energy, and each card requires a different amount of energy to be used. When the player ends his turn, all unused cards will be sent to the discard pile. When all the cards in the draw pile are used up, the discard pile is reshuffled and returned to the draw pile. 

There are many different types of cards in the game, with two main characteristics: "color" and "type". For example, cards of "Attack" type will cause direct damage to the enemy; "Skill" cards are auxiliary in nature and will not cause damage at the moment, while some skill cards can increase Some skill cards can be used to reduce damage by increasing their "slot value", which usually only works for one turn, while others allow the player to draw new cards; "ability" cards have effects that last for the duration of the battle and disappear directly after use without entering the discard pushes. "Status" and "Curse" can cause negative effects on us, such as dizziness and burn, which normally cannot be played and take up space in the hand. Each battle is won with random money, cards or potions. 

In addition, there is also the "Relic" system, which has a significant impact on the game. Relics allow players to gain various benefits, such as automatic life restoration at the end of a battle, the ability to draw two more cards at the beginning of a battle, immunity to negative status, and so on. Each character will receive an exclusive relic at the beginning of the game, and there are opportunities to obtain new relics by defeating enemies or participating in random events.

The game also has the "randomness" of Roguelike, as the map, enemies, cards, and events are randomly generated each time you start the game, and once you die in battle, you can only start a new game from the beginning, with no way to go back. However, even if you fail, you may leave some permanent achievements, not worthless. After death in battle, a score will be settled, and the game will be scored for the extent of map exploration and the number of enemies killed, and new cards, props and events will be unlocked when a certain score is reached.

In addition to the standard adventure mode, the game also offers a daily challenge mode that allows players to use officially limited characters or cards to go on adventures with the goal of scoring higher and competing with other players.
