Dungeon Solitaire is a narrative fantasy card game. With each turn you defeat monsters, disarm traps, open doors, and explore mazes as you delve the depths of a dark dungeon. The original game, Tomb of Four Kings, used a standard deck of playing cards, and is still available free on my website.
Now the game is being expanded to use a 78 card tarot deck, plus up to 12 additional cards used in an advanced version of the game. And these new rules will be paired with a custom illustrated dungeon-themed tarot deck exclusively created for the Labyrinth of Souls.
