Mysticana: Cave of DjinnsExpansion

From BoardGameGeek:

For those who stumble into the Cave of Djinns, there is only one way out. Should you fail to solve the djinns' riddles, you will surely suffer their wrath. Cave of Djinns is a solo-only 6-card expansion to the Mysticana deck. In this evolving puzzle, the player must solve the djinns' riddles through careful card placement. Each of the 6 double-sided djinns are placed in a loose pyramid shape, with space around each djinn to play a card in each orthogonal direction. The player draws 2 cards and plays them both in sequence each turn. Each djinn shows a specific arrangement of cards around them which must be fulfilled to solve their riddle and earn an immediate one-time bonus. Solved djinns are covered by an adjacent Mysticana card. Complete all 6 riddles to escape the cave with wits intact! Cave of Djinns is a solo tile-laying puzzle with action-chaining. Mysticana is a Foundation Deck: an 18-card deck that includes multiple core games using just the base cards with even more games added through small expansions. The deck features cards with 6 ranks across 3 suits (elements) which have a “rock-paper-scissors” hierarchy. While each game might make use of the deck's design in different ways, the flexible foundation enables new games to fit in seamlessly alongside previous entries.
