Slide · fuse · reach Gold
Fuse opposites. Reach Gold.
Aurifex is a slide-and-merge puzzle with a twist: tiles only fuse when Sun meets Moon. Slide the board, pair opposite poles of the same substance, and climb the Celestial Ladder from Prima Materia all the way to Gold — and beyond it, to the Stone.

The rule
Only when Sun meets Moon.
The board teaches as you play: attraction threads show which tiles can fuse.
-
Pair opposite poles
Same substance, opposite pole, and the tiles fuse one step up the ladder.
-
Conjunctions
Every few swipes a Conjunction lets any two of the same substance meet.
-
Fill the Heat
Chain fusions to fill the meter; on a full one, the next fusion climbs two steps at once.
