Not Touching: Logic Puzzle

One per row. One per column. One in every colour. And none of them may touch, not even at a corner. Not Touching is a cozy logic puzzle with a promise most puzzle games can't make: every board has exactly one answer, proven before it ships, and you can always reach it by thinking. You never have to guess. HOW IT PLAYS • Tap a square once to mark it with an X. Double-tap to place a piece. • Drag across squares to mark several at once. • Place one piece in every row, every column and every coloured region. • No two pieces may touch, sideways or diagonally. FOUR WAYS TO PLAY • The Road: 2000+ levels, from gentle 6×6 boards up to 12×12. Earn up to three stars on each. • Daily: one new board every day, with your streak and your best run. • Zen: endless calm boards with instant feedback and no penalties. • Rush: three minutes. How many boards can you settle? HINTS THAT TEACH Stuck? Ask for a hint. First you get a nudge towards where to look, then the reasoning, then the exact squares. Hints come from the same step-by-step logic that proves each board, so they never guess either. Solving a board does not refill them. When you run out, you can watch an optional ad for one more hint or one more reveal. A campaign attempt that runs out of hearts can watch one for a single heart back. DIFFICULTY YOU CAN TRUST Every board is graded by the logic it actually takes to solve, not by a label. Early levels need only simple steps; later ones ask for the clever deductions. LOOKS Play with cuddly cats, or switch to a moonlit hollow of friendly ghosts. Switching changes the look around the board you are playing; it never changes the puzzle.
