Crystallo: Den of Dragons is an expansion for Crystallo for 1 player, 30–40 minutes per game, and ages 8 and up. It was designed by Liberty Kifer and its main mechanics are Set Collection, Tile Placement, and Pattern Building.
Crystallo: Den of Dragons adds a new layer of puzzle-solving adventure to the second (dragon) phase of Crystallo. In addition to capturing the Black Dragon, players can choose an additional dragon to do battle with (Mystic, Armored, or Golden.) Polyomino treasure tiles must be placed on top of and within the confines of the dragon puzzle, adding another dimension to the challenge. Defeat both dragons and earn impressive bonuses to your score; fail at either one, and both escape! —description from the publisher
Crystallo: Den of Dragons supports 1 player according to the catalogue. This is the publisher’s listed player count, so the game is designed for exactly that number of participants. Variants for other group sizes, if any, are described in the rulebook of your edition, so check it before setting up a different configuration.
The listed playing time for Crystallo: Den of Dragons is 30–40 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
The catalogue lists Crystallo: Den of Dragons for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
