PangPangChemy vs Elements

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.

Elements turns the periodic table into short quiz rounds you can finish in a couple of minutes — on the bus, between classes, or the night before an exam. Ten questions per round. Every answer is shown immediately, and anything you miss goes to your review list so you drill the elements you actually get wrong instead of the ones you already know. FOUR WAYS TO PRACTISE - Symbol to name: see Fe, pick Iron - Name to symbol: see Iron, pick Fe - Atomic number: which element is number 26? - Element groups: metal, halogen or noble gas? THREE DIFFICULTY RANGES Start with the first 20 elements, move up to 36, then take on all 118. THE WHOLE TABLE Tap any element to see its atomic number, period, group and category. Categories are colour coded, so the shape of the table makes sense at a glance. WORKS ANYWHERE No account, no sign-up, no internet. The app makes no network requests at all, so it works in airplane mode and in an exam room. Your best score and your missed elements stay on your device — the App Store privacy label reads "Data Not Collected" because nothing is collected. FREE AND PAID The free version covers the first 20 elements in symbol-to-name mode, plus the full table and mistake review. One payment unlocks all 118 elements and all four quiz modes. No subscription, ever. Built for students, teachers and anyone who wants the table in their head rather than on a poster.
