Pictopix Logic puzzles that never need guessing

Every puzzle in Pictopix can be solved by deduction alone. No guessing, no dead ends that only luck can fix: the numbers along the top and left tell you everything, and the answer is always reachable with careful thought. A row reads 3, 1, 4, so you mark squares, cross out the ones you have ruled out, and slowly the picture assembles itself. When a big grid finally clicks into place and the finished image appears in color, the payoff is real. If you get stuck, hints are there, and three difficulty settings let you decide how much help the game gives: from highlighted rows to none at all. Undo, redo and temporary marks keep mistakes cheap.

The built-in puzzles start small at 5x5 and grow to 40x40, with over 300 to work through, plus a tutorial that teaches the rules as you play. Beyond Classic mode there are Mosaics, where several puzzles combine into one larger picture, Endless mode for a fresh grid whenever you want one, and timed Challenges for a change of pace. Then there is the editor: draw your own puzzles and share them on the Workshop, where players have published thousands more, all checked to be logically solvable. Puzzles can be paused and resumed at any time, so a big 30x30 can sit half-finished while life happens. There are also hidden secrets tucked away for those who poke around.
