Alchemy Blocks is a free browser puzzle game where you slide elemental tiles on a 4×4 grid and trigger chemical reactions. Merge Earth, Fire, and Water to climb the reaction chain — Stone, Magma, Metal, Gold — and ultimately forge the legendary Philosopher's Stone. No download, no login, no account required.
Swipe or use arrow keys to slide all tiles in one direction. When two compatible elements collide they transmute: two Earth tiles become Stone, two Fire tiles become Magma, Stone plus Magma forges Metal, two Metals create Gold, and two Gold tiles produce the Philosopher's Stone — victory. Fire meeting Water produces a Steam reaction that clears the entire row or column you swiped along instantly. The Stability Meter tracks lab pressure — keep it above zero by merging dangerous tiles and keeping space open.
Every day a new global puzzle is generated from the date. Every player starts with the exact same board configuration and tile sequence — making scores directly comparable worldwide. Can you complete today's Daily Challenge in fewer moves than everyone else? The puzzle resets at your local midnight.
Infinite Mode — free-play, no move limit. Push for your personal best score. Classic Mode — reach the Philosopher's Stone under tighter stability constraints. Daily Challenge — one globally shared puzzle per day, scored by move count. Your progress is saved across sessions so you can resume where you left off.
