Nani Dungeon

Nani Dungeon is a solo game where you as an adventurer go through a dungeon by playing item cards in ascending or descending order to gain item cubes to defeat monsters. Each dungeon card has specific conditions to fulfill that corresponds to the color of the cubes. Once fulfilled, you defeat the monster and advance to the next dungeon card. You win if you reach the end of the dungeon with the treasure chest and you'll lose if the Dungeon Master or Boss is in the same location as you or reaches to the treasure chest before you.

—user summary

There are various dungeons in the world-towers, caves, underground labyrinths, floating islands, and more. But why are these called dungeons? It's because all dungeons have two things in common: a Dungeon Master and treasure. The Dungeon Master is far too powerful to confront easily, but the treasures they guard are so alluring that many adventurers still venture forth into "some(nani) dungeon" risking everything for the promise of a bright future.
