Palmo: Number Weave

Palmo is a puzzle about regions. The board holds numbered squares; each one starts a patch, and its number is how many cells that patch takes: a 4 takes four cells, a 9 takes nine. Close the whole board and the level is done.

ONE RULE
Touch a numbered square, then take neighboring cells one at a time. The counter on the square drops with every cell. At zero the patch settles and seals itself. There is no fifth cell for a 4; the board will not let you take it. Cells are neighbors edge to edge, never corner to corner.

THREE EXTRA STROKES
A settled region can be unpicked: hold your finger on it until it comes apart, then draw it again. Each unpicking burns one of your three extra strokes. Whatever is left when the board closes turns into stars, so three stars mean every region was right the first time.

WALLS AND STONES
A wall cuts between two cells and no region crosses it. A stone is never taken: it stays outside the weave and the cells around it have to manage without it. The board teaches both by itself, in the level where they start to matter.

ONE SOLUTION
Every board in Palmo has exactly one correct weave. A solver went through all 252 levels and found no second answer. That is the point: a board with two answers says think and means guess.

NO WORDS ON THE BOARD
The playing screen carries no text. The lesson is in how the board is built: a new idea arrives in the level that will not come out without it. If you stop, Palmo points at a cell instead of explaining it, and the pointer comes from the solver, not from a hunch.

Same family as Fillomino and Shikaku: the number tells you how big the region has to be.

Level 1 is a three by three board with a single 9. The whole rule is in there.
