Push elements together and watch real chemistry happen. PangPangChemy is a chemistry puzzle played on a 6x6 board. Swipe to slide element tiles around, and when a reacting pair meets, it becomes a compound. H and O make water (H₂O). Na and Cl make salt (NaCl). Every reaction in the game is a real one. HOW TO PLAY - Swipe up, down, left or right to move every tile - When two reacting tiles meet, they merge into a compound - Compounds become ingredients for even more complex substances - The game ends when no move changes the board FEATURES - 16 elements, 50 compounds, 48 reactions - Compound book: track everything you have discovered. Undiscovered entries stay as silhouettes with a hint like "2 elements" - Every first discovery opens a card with a one-line chemistry fact - Element Music Box: compounds made with flame-test elements (Na, K, Ca, Cu) engrave notes on a music-box cylinder. Wind it up to hear the tune you built - Flame-test glow: the board lights up in each element's real flame color - Reaction log under the board shows every reaction as an equation - Daily challenge: a new target compound each day, with a streak counter - One undo per run, so a single misread swipe is not fatal - P (phosphorus) is a bomb tile that clears everything around it - 7 languages: English, Korean, Simplified Chinese, Traditional Chinese, Japanese, German and French MADE FOR - Students curious about chemistry, and adults who want to revisit it - Anyone who likes merge puzzles but wants to walk away having learned something - Anyone who wants to focus without ad interruptions PLAY WITH PEACE OF MIND - Fully offline, no internet connection required - No ads, no in-app purchases - No sign-up, no personal data collected Water, salt, sulfuric acid, marble, and the reason silver turns black. Fill all 50 pages of the book.
