Molecule: Logic Grid Puzzle

Fire rays into the grid. Deduce where the hidden atoms lie. Bond them together to synthesise over 100 real-world chemical molecules!

Molecule is a sleek, zero-luck scientific deduction puzzle that blends classic ray-tracing logic with the thrill of chemical discovery and a competitive Global Daily Challenge.

SYNTHESISE REAL MOLECULES
Every puzzle hides a secret arrangement of atoms. Once you pinpoint every hidden atom on the board, watch them forge glowing covalent bonds and synthesise into an authentic molecule—from Water (H₂O) and Oxygen (O₂) to Caffeine, Benzene, and TNT!
• Build Your Molecular Codex: Unlock and collect 110+ authentic chemical compounds with 3D ball-and-stick geometry, rarity tiers, and real scientific facts.

THE GLOBAL DAILY CHALLENGE
Every midnight, one shared mystery grid drops for everyone around the world.
• One Shared Board: Everyone faces the exact same arrangement of hidden atoms and target molecule.
• Beat Par & Climb the Podium: Solve with the fewest rays and fastest time to claim Gold, Silver, or Bronze on the Global and Friends Leaderboards.
• Protect Your Daily Streak: Build your consecutive solve streak and track your friends' live discoveries.

PURE DEDUCTION. ZERO LUCK.
You can't see the atoms directly—you can only observe how your test rays behave when fired into the grid:
• Direct Hit (H): Your ray strikes an atom head-on and is absorbed.
• 90° Deflection: Passing adjacent to an atom bends your ray 90 degrees before it exits at a numbered port.
• Reflection (R): A ray caught between atoms or deflected at the grid edge bounces straight back out.

Use pure logic to trace the paths, mark empty coordinates, and pinpoint every atom without guessing.

RISE THROUGH THE SCIENTIFIC RANKS
• Interactive Guided Lab: Synthesise your first molecules in seconds with a hands-on, step-by-step introduction.
• Scalable Grid Sizes: Progress from quick 5×5 warm-up grids to deep 8×8, 10×10, and 12×12 mental marathons.
• Academic Progression: Advance from Lab Assistant to Junior Physicist, Mad Scientist, Nobel Laureate, and Chief Scientist.
• Extreme Mode: Ready for the ultimate test? Play with hidden ray numbers and rely on pure spatial mastery.

Step into the lab, fire your first ray, and discover what molecule is hiding on today's grid!
