Generator for trees logic puzzles.

Requires Uiua v0.10.

Below is an example puzzle.

The rules are as follows:

• Each square either contains a "tree" or does not contain a tree (there is no significance to the object in question being a "tree," it is really just an arbitrary object occupying one cell).
• Every row, every column, and every colored region contains exactly one tree.
• Two trees cannot be adjacent to each other, even diagonally.

Since this specific puzzle is 8x8, there are a total of 8 trees; solve the puzzle by finding them.

Example usage

Generate an 8x8 puzzle and play it with the app.

uiua gen.ua 8
uiua app.ua

Generate

• file defaults to out.csv

uiua app.ua [file]

In the app, left/right click on squares to cycle between eliminated (-) and tree (T). Press space to reroll the colorscheme.
