About

MeowSolver

Features
Read full description

MeowSolver is a lightweight utility that solves placement logic puzzles. The kind where every row, column, and color region gets exactly one cat, and no two cats can touch, even diagonally. Instead of entering clues one by one, you paint the entire board yourself. Pick a grid size from 5×5 to 10×10, choose a color from the palette, and drag across cells to fill in regions. When your board matches the puzzle you're working on, tap Solve. The algorithm finds a valid placement in seconds and shows you exactly where each cat goes. HOW IT WORKS: Set your grid size (5×5 through 10×10) Select a color and drag to paint regions onto the grid Tap Solve, and cats appear on the board instantly Tap Clear to start over with a fresh grid BUILT FOR SPEED: The solver uses a constraint-based backtracking algorithm that prunes invalid branches early. Even large 10×10 boards resolve quickly. NO DATA, NO ADS, NO ACCOUNTS: MeowSolver runs entirely on your device. Nothing is collected, nothing is tracked, nothing is sent anywhere. Open the app, solve your puzzle, move on.
