A workbench, a cardboard game board & a pile of paper pieces.

Every puzzle piece in KNICK is a chain of paper segments held together by fasteners. Each fastener is a hinge: pieces can be folded, turned, taken apart and put back together. A flat chain becomes an angle, a hook, or a staircase — whatever you're still missing to solve the level.

The first levels come easy. Later on, it takes a few detours in your head before everything fits just right.

• 120+ levels across six chapters

• Four moves: fold, turn, split, join. No new rules along the way — each chapter poses a different, challenging task with the same tools

• A daily puzzle on the side

• No timer, no score, and you can undo any misstep at any time
