Crystallo + Expansions

🎯 The Goal

A solo logic puzzle where you use a wicked Black Dragon’s own elemental crystal magic against him to liberate six captured mythical creatures before turning the tables to trap the beast in his own lair[cite: 9].

⚙️ Core Actions

The game utilizes a deck of 54 cards and a pool of 18 tracking gems split across two distinct gameplay phases[cite: 9]:

• Grid-Based Card Placement: Draw a Cavern Card and position it horizontally or vertically[cite: 9]. To place it validly, at least one of its crystals must touch an existing crystal on the table; cards can overlap or sit side-by-side, but orbs can never overlap other icons[cite: 9].
• Form Logic Squares: Arrange a $2\times2$ square consisting of exactly three crystals and one colored orb[cite: 9]. The three crystals must satisfy standard set logic—meaning their shapes and colors must either be all identical or all completely different[cite: 9].
• Free the Creatures (Phase 1): Successfully completing a crystal set “lights up” the orb in that square, allowing you to remove a gemstone bond from the corresponding colored creature card[cite: 9]. Removing all 3 gems frees that creature[cite: 9]. You must free all six creatures before the deck runs out to advance[cite: 9].
• Unearth Hidden Treasures: Nine specific cavern cards feature special dual-orb layouts[cite: 9]. Lighting up both orbs collects that item for endgame points and unlocks set bonuses like extra Phase 2 cards or immediate gem removals[cite: 9].
• Trap the Black Dragon (Phase 2): Clear the table and reveal the Black Dragon card[cite: 9]. Take your reserved hand of cards (consisting of 9 pre-selected cards plus any leftover from Phase 1) and turn them face up[cite: 9]. You must construct matching crystal sets using these remaining cards to light up and seal all 6 orbs on the dragon’s card before your pool runs dry[cite: 9].

🧠 Why you’ll like it

It is a brilliant, space-efficient spatial puzzle that masterfully translates classic grid-matching logic into a beautifully stylized card game[cite: 9]. The scoring system creates a fantastic mechanical tension: rushing to complete simple crystal sets lets you free creatures quickly, but meticulously weaving complex networks allows you to link crystals across multiple overlapping sets to unearth high-scoring treasures[cite: 9]. It offers a deeply satisfying tactical loop that is quick to set up but rewards repeated plays as you learn to manipulate card layering[cite: 9].
