Floor Plan

Floor Plan is a minimalist logic puzzle inspired by architectural blueprints.
Each cell on the grid shows a number — that number tells you exactly how many walls must touch it from the four sides. Your job is to fill in the missing walls so every number in the layout is satisfied.
Simple rules. Surprisingly deep puzzles.

How to play
• Numbered cells are fixed clues — they cannot be changed.
• Fill in the blank cells with wall numbers (1–4) or mark them as empty floor (X).
• A clue is satisfied when the count of adjacent walls matches its number exactly.
• The same wall number cannot touch another of the same value directly.
• When every clue is satisfied, the floor plan is complete.
