Free puzzle games

Free puzzle games in your browser, from pen-and-paper logic to calm sorting games. The logic shelf has sudoku and killer sudoku, kakuro, nonograms, bridges, loop puzzles, a daily chess puzzle and a whodunit to reason out. The casual shelf is for winding down: sort water and shelves, slide blocks out of the way, connect pipes, fit tangrams, merge numbers, or put together a jigsaw cut from a new picture every day.

Brain and memory games round it out: a daily ten-question quiz, a country to name from its outline, pairs to match and a mental math duel you can play against a friend. Many puzzles are daily, with a fresh one each day and a streak to keep; the rest you can replay as often as you like. Your stats stay on your device, there is nothing to install, and each puzzle is made to fit a phone screen first.
