Cosmic Donsol

Cosmic Donsol is a cosmic re-theme of Donsol, a minimalist dungeon-crawler card game designed by John Eternal.

A standard deck of 54 playing cards (including jokers) is the dungeon. You draw 4 cards to form a room and must survive by carefully using potions, shields, and combat choices. The original mechanics are preserved, with a new cosmic setting and planned cosmic horror vibes 🐙

Rules Overview

• The deck is the dungeon.

• Draw 4 cards to create a room.

Only the first potion in a sequence heals.
Face cards (J, Q, K, A) are worth 11.

♦ Diamonds — Shields

Escaping Rooms

When escaping, remaining cards go to the bottom of the deck.

• Hell: Escape only when all monsters are defeated.
