Background and Worldview: An ice castle within the Arctic Circle has been attacked by fireballs from a Balrog, and the ice crystals are melting. Players, as guardians of the ice, must match snowflakes and ice crystals to reinforce the castle, stop the fireballs from spreading, and finally summon the aurora to restore the eternal freeze.

Core Gameplay: Freeze and match threes. Matched ice crystals will become a harder “permafrost layer,” requiring another match to completely eliminate them. Flames will spread to adjacent tiles; they must be eliminated before they reach the castle. Each level’s objective is to protect the castle’s durability.

Special Features: Aurora energy bar; consecutive matches summon the aurora to freeze all flames at once.

Visuals and Sound Effects: Blue and white tones, light reflecting off the ice surface, falling snowflakes. The soundtrack features wind chimes and synthesizer pads, with snow-walking sounds.

Number of levels: 890 levels Level descriptions: Levels 1-85: Frozen Lakeside, learn the mechanism of freezing flames; Levels 86-270: Iceberg Tunnel, narrow passages; Levels 271-550: Flame Demon Outpost, flames spread rapidly; Levels 551-890: Aurora Dome, the final battle between ice and fire.
