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

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.
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.
Changes apply immediately to the current game.
