How to play
Sudoku logic × 2048. One swipe moves every board at once.
MergeSwipe, arrow keys or WASD. Equal tiles slide together and double — 2 → 4 → 8 → 16… — but tiles never cross the thick walls.
The lawTwo equal 64+ tiles in the same macro row/column but in different boards get pinned — frozen solid. Tap a pin to spot its twin.
Break itMerge a pinned tile with a match from its own board to dissolve the conflict — or pin on purpose to lock your biggest tile in a corner.
FractureA gridlocked board turns to stone — inert, but it still pins others. 3 stone boards ends the run (change it in Settings). Free its pin to revive it.
SpawnsGold-ringed boards are armed to spawn; the ghost cell shows exactly where. Cover a ghost to relocate that spawn.
PowersScore to unlock 8 powers in the bar. You get 10 undos + 2 revives per run. Move, Fuse & Walless cost more each reuse.
WinHit the target on any single board: 2048 on 4×4 boards, 512 on 3×3.
Settings
Lets the AI take over and play when the board sits idle. Turn it off to save battery.

Board layout
Changing the layout starts a fresh game. 3×3 is the original hard mode.
Constraint threshold
Tiles below the threshold never pin. Lower = tighter, more Sudoku pressure.
Music genre
A genre makes your run compose a song: every merge, spawn and swipe lands on a beat grid with that genre's chords, bass and drums — and each new game rolls its own key, tempo and progression (surprise rolls the genre too). Genres override the melody, swipe and tempo choices below during live play; classic keeps the original sounds, and song replays always use them.
Melody sound
The instrument for merge and spawn notes. "Off" keeps drums and effects only.
Song playback speed
How fast your run replays as a song (the "♪ My song" button and leaderboard ▶).
Swipe sound
Each of the four swipe directions plays a different pitch of the chosen sound.
Spawn density
How many of the boards that moved get a new tile after each swipe. Fewer = calmer.
Losing
A gridlocked board turns to stone — grey, inert, but its tiles still pin. Sudden death: one stone board ends the run. 3 fractures: lose at three. Last stand: lose only when everything is stone. A stone board revives if the pin choking it dissolves.
