Muros

Muros is built on Tapa, a shading puzzle. Clue cells hold one or more numbers, and each number is the length of a run of shaded cells among the eight squares around that clue. Your job is to decide which cells to fill. Three rules hold: the shaded cells around each clue must match its numbers exactly, all shaded cells must join into one continuous wall, and no 2x2 block may be completely shaded. Every puzzle has exactly one solution and never needs a guess.

The Daily Puzzle is a fresh 15x15 grid every day, the same for every player, so you can compare times with friends. Solving it day after day builds a streak.

Outside the daily there is an Adventure of hand-made levels arranged in chapters, starting with small 5x5 grids and growing to large boards, with up to three stars a level. Free Play generates endless puzzles at easy, medium, hard and expert sizes from 5x5 to 15x15. You tap to cycle a cell or drag across the board to shade and clear quickly, and the puzzle screen has a timer, hints, undo and a clear button.

Muros comes from Ravenhold LLC and came out in April 2026. It suits players of nonograms, nurikabe, slitherlink and minesweeper who like a long, careful solve.
