About this game

🧪 BUILD REAL MOLECULES. LEARN REAL CHEMISTRY.

Ever wondered how water (H₂O) is made? Or what caffeine looks like at the molecular level?
ChemLab is a chemistry puzzle app that lets you drag atoms, create bonds, and build real molecules through hands-on gameplay.

From simple hydrogen gas to complex vitamins and amino acids, explore molecular structures through 150 handcrafted chemistry puzzles designed to teach how atoms connect in the real world.

🎮 WHAT YOU’LL DO IN CHEMLAB

✓ BUILD 150+ REAL MOLECULES
Start with water and progress to caffeine, glucose, amino acids, and DNA bases. Every molecule you build represents a real chemical structure.

✓ 30 THEMED CHAPTERS
• Water & Simple Molecules
• Carbon Chemistry
• Alcohols & Acids
• Ring Structures
• Amino Acids & Proteins
• Fuels & Polymers
• Medicines & Vitamins
• DNA Building Blocks
…and more.

✓ LEARN AS YOU PLAY
Each puzzle includes short facts about the molecule you’re building, helping you connect structures with real-world chemistry.

✓ INTERACTIVE PERIODIC TABLE
Browse elements, valence electrons, atomic properties, and bonding rules using a built-in reference.

✓ CHEMISTRY LESSONS
Six structured lessons explain single, double, and triple bonds and how atoms form molecules.

📚 SUITABLE FOR

• Students studying chemistry
• Teachers using STEM learning tools
• Parents looking for educational puzzle games
