A logic block puzzle with gravity — where the 3-star target is a proven minimum, not a designer's guess.
No install. No sign-up. The full game runs in any modern browser.
Every board ships with a machine-checked proof.
The 3-star target is the real minimum number of moves, found by a solver before the level ever shipped. If it says six, then six is possible and five is not. When the board says a special move is required, that exact claim was verified too.
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.
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.
