Every level in FALLMATCH comes with a machine-checked mathematical proof. It shows the fewest moves the level can be solved in. Match that number and you earn 3 stars, the top score.
No install. No sign-up. The full game runs in any modern browser.
Each level is proven by a solver that tries every possibility.
Before a level ships, the solver finds the fewest moves it can be solved in. If it says six, then six is possible and five is not. When a level says a special move is required, that exact claim was verified too. If the proof can't be finished, the level doesn't ship.
Even the ten difficulty tiers are computed — from search depth, how narrow the winning path is, and how easily one careless move kills the board. In most puzzle games difficulty is a feeling. Here it is a measurement.
The game shows it too: the win card tells you when you hit the proven minimum, and a How We Prove It page shows, in seven lines, how every level is proven.
Push a block left or right and matching patterns clear the moment they touch. Then everything above falls, and the board you were looking at is gone — replaced by the one your move just created.
That is the whole game, and it is enough to get very hard. There is no timer and no lives. Think as long as you like.
⟳ Rotate — gravity itself turns 90°, the board reshapes, and the blocks resettle. Two rotations solve this one.
Turn gravity itself 90°. Everything falls somewhere new.
A pulse flips the whole board upside down.
One motion, and you are looking at a different puzzle.
Some frames are broken. A block that slides through one is gone for good.
Sixteen chapters, VERY EASY to NIGHTMARE. Special moves unlock as you go.
Ten rungs, one per difficulty tier. Stars are the score, 30 is a perfect run, and leaving a board ends it. No hints.
One fresh board a day, the same for everyone. Keep a streak and it pays you back in hints.
One harder board every Monday, also shared by everyone. Opens once you have 30 stars.
Most of what makes a puzzle game stressful is not the puzzle.
Everything above is free — all 900 boards, every mode. If you want more there is a one-time Premium unlock and hint packs that never expire. That is the entire business model, and the game plays offline either way.
It takes about ten seconds to find out whether this is your kind of puzzle. No install, no account.
