Picross
Reveal patterns using row and column clues. Racing, action, puzzles and duels to enjoy on phones or computers.
Each number gives the length of a consecutive group of black cells. Read row clues from left to right and column clues from top to bottom. Leave at least one blank cell between groups; blanks may also appear at either end. A 0 clue means that entire row or column is empty. Early levels introduce full lines, empty spaces and separated groups. Choose Fill, Cross or Erase, then tap a cell. Applying the same mark again clears it. Crosses are optional notes: to win, fill every black cell and no other cell. Mistakes never cost lives and there is no timer. Clues change appearance when the visible runs match their numbers; this does not check their positions against the solution. Reveal one cell reads the solution, first corrects a wrong mark or fills an unfilled black cell, and identifies its location. Undo restores the exact previous action, including a reveal or the winning mark. Restart and New game use the shared confirmation prompt; completed patterns stay earned. Completing a level unlocks the next. Arrows navigate; Space or Enter applies the selected tool; F, X and E fill, cross and erase; Delete erases; U or Z undoes. Pause, switching windows or hiding the page locks the grid until Resume. The exact grid, history and progress are saved.
