Logic games you can play in your browser
Logic games are most satisfying when every move produces useful evidence. These browser picks span compact puzzles and longer systems: classify suspects in Clues by Sam, mentally reverse paper folds in Daily Unfold, learn Dungleon’s hidden fantasy rules, build words while steering Snibble, or confront a sixteen-quarter AI competition scenario in Critical Window.
