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 step by step — from Prima Materia all the way to Gold, and beyond it to the Stone. The board explains the rules as you play: attraction threads show which tiles can fuse, and every few swipes a Conjunction lets ANY two of the same substance meet. Chain fusions to fill the Heat meter — on a full meter the next fusion climbs two steps at once (IGNIS). MODES • The Great Work — a campaign of 42 hand-tuned levels in 7 chapters. Every level has a proven best solution: chase par and three stars. • Classic — an endless run with rising difficulty, micro-goals and the magnetic law from the first move. • Daily Challenge — one puzzle a day, the same for everyone, seeded from the date. Keep your streak alive. MORE TO DISCOVER • Codex — every rung of the Celestial Ladder and its lore. • Leaderboards — Daily, Weekly and All-time boards. Play as a guest or sign in with Apple or Google to claim your name. • Share a result card with a link your friends can open. • Resources that bend the rules: undo a move, or flip a tile's pole. PLAYER-FIRST • Fully playable offline and as a guest — sign-in only adds cloud save and the leaderboards. • A unique, hand-drawn look — every symbol is original artwork. • Available in 9 languages: English, Hungarian, German, French, Spanish, Italian, Portuguese, Romanian and Russian. • Your data is yours: delete your account and all cloud data from inside the app at any time. Fuse opposites. Reach Gold. Become the Aurifex.
