Alchemy Blocks — A Free Elemental Fusion Puzzle Game
Alchemy Blocks is a free browser puzzle game played on a 4×4 grid. You slide elemental tiles together to trigger chemical reactions, climb the transmutation chain — Stone, Magma, Metal, Gold — and try to forge the legendary Philosopher's Stone. It runs entirely in your browser: no download, no login, and no account. The game above is the full version, and everything below explains exactly how it works, from the basic controls to the strategy that separates a stalled board from a perfect run.
How to Play
Swipe, or press the arrow keys or WASD, to slide every tile in one direction at once. Tiles travel until they hit a wall or another tile. When two compatible elements collide they react and transmute into the next element up the chain. After each move a new tile — Earth, Fire, or Water — spawns in a random empty cell, so open space is the resource you are really managing.
- Merge matching elements. Two Earth tiles become Stone; two Fire tiles become Magma.
- Combine up the chain. Stone plus Magma forges Metal; two Metal tiles make Gold.
- Vent pressure with Steam. Merging Fire with Water clears the entire row or column you swiped along — your best recovery tool.
- Watch the Stability Meter. Isolated high-tier tiles stress the lab; keep them paired with merge partners and keep space open.
- Forge the Philosopher's Stone. Two Gold tiles merged together sit at the top of the chain, and win the run in Classic and Daily Challenge.
The Reaction Table
Every merge is decided by which two elements collide, not merely whether they match:
| Element A | Element B | Result | Type |
|---|---|---|---|
 Earth | Earth |  Stone | Evolution |
 Fire | Fire |  Magma | Evolution |
| Stone | Magma |  Metal | Evolution |
| Metal | Metal |  Gold | Evolution |
| Gold | Gold |  Philosopher's Stone | Victory |
| Fire |  Water | Steam — clears the swiped row or column | Utility |
| Water | Water |  Ice — frozen for 5 turns | Hazard |
Tiles with no compatible reaction simply block each other — they stop on contact and neither merges, wasting both the move and the space. Two Stone tiles, for instance, do not react. Planning which collisions actually produce something is the heart of the game.
Game Modes
Infinite Mode
Free play with no move limit and no win screen. The Philosopher's Stone is simply the ultimate tile, and you keep going to push your score as high as possible. A run ends only when the board locks up or the lab destabilises completely.
Classic Mode
The goal-oriented mode: reach the Philosopher's Stone within a budget of 100 moves. Creating it ends the run in victory; exhausting the budget first loses the run. Because unused moves convert directly into score, efficiency matters as much as survival.
Daily Challenge
One globally shared puzzle per day, generated deterministically from the calendar date with no server involved. Every player worldwide receives the identical sequence of tiles in the identical positions, so scores are directly comparable. It runs under Classic rules, including the 100-move budget, and a fresh puzzle arrives each day at your local midnight.
Scoring
In Classic and Daily Challenge your final result combines two things. The Alchemy Score rewards every reaction you trigger, with higher-tier elements worth substantially more — a Philosopher's Stone dwarfs a Stone. The Speed Bonus awards 100 points for every move you did not use. Your Total Score = Alchemy Score + Speed Bonus, and it is banked as a high score only if you actually win: running out of moves records nothing, no matter how high the alchemy total climbed. Infinite Mode has no budget, so there your score is simply the alchemy total.
The Stability Meter
The Stability Meter reads the whole situation on your board rather than counting dangerous tiles. It is recalculated after every move from how much open space remains, whether your tiles can react with their neighbours, and whether a Fire-and-Water steam escape is available.
Open space is the biggest factor — empty cells act as escape valves, so a roomy board reads calm regardless of what sits on it. The second factor is resolvability: a high-tier tile parked beside a partner it can merge with is largely defused, because you can clear it next move. The same Gold tile is reassuring next to another Gold and alarming when stranded alone. A Fire beside Water reads as an outright positive, since it is an escape you can trigger at will.
The practical lesson: do not panic at the raw number of high-tier tiles — panic when they become isolated on a crowded board.
The Void Blast
The Void Blast is an optional power-up available beneath the board whenever more than one tile is in play. Activate it, watch a short rewarded advert, then tap any single tile to remove it from the grid entirely — it does not cost you a move. It is at its most valuable when one stray tile is separating two Gold tiles that would otherwise merge, or when a frozen Ice block is strangling an already crowded board. In Daily Challenge it is capped at two uses per run, so the shared puzzle stays a fair comparison between players; Infinite and Classic have no limit. Treat it as an emergency lever rather than routine tidying — spending it early on a comfortable board wastes the one tool that can rescue a run that looks lost.
Strategy Tips
- Anchor your best tile in a corner. Pick a corner for your most advanced tile and avoid the swipe direction that would pull it away. Central high-value tiles are far harder to protect.
- Avoid accidental Ice. Merging two Water tiles creates Ice, which cannot be merged for five turns and occupies a cell you usually cannot spare.
- Save Steam for a blocker. A Steam reaction is most valuable clearing the one tile standing between two Golds, not as routine tidying.
- Do not waste swipes. In budgeted modes a move that merges nothing still costs you 100 points of Speed Bonus.
Frequently Asked Questions
Is Alchemy Blocks free to play?
Yes — entirely free in any modern browser, with no download and no account. The game is supported by advertising.
Why did my game end when the board was not full?
Either the Stability Meter reached zero, which happens when high-tier tiles pile up isolated on a crowded board, or — in Classic and Daily Challenge — you used all 100 moves before forging the Philosopher's Stone.
Does every player get the same Daily Challenge?
Yes. The puzzle is derived from the calendar date itself, so two players anywhere in the world solve an identical board and can compare scores directly.
Are my scores saved?
High scores for each mode are stored in your browser's local storage. There is no account or cloud sync, so clearing your browser data resets them.
Can I undo a move?
There is no undo in the free version.
