Puzzle Games With No Need for Fast Reflexes

A difficult puzzle can give you all the time you need to think. These recommendations focus on untimed main puzzles, discrete moves or evidence you can revisit, covering spatial problems, number grids and investigations. Some are severe tests of reasoning; a few offer a gentler change of pace. The notes identify useful undo, hint and interface tools, and distinguish optional timed challenges where they exist. First-person walking, fine grid symbols and audio-heavy clues are mentioned when they affect how you will actually use the game.
