Logic Puzzle Games

38 free games in this category

If you like a puzzle that can be solved by pure reasoning, start here. Number puzzles include Sudoku, Killer Sudoku, Kakuro, Futoshiki, MathDoku, Skyscrapers and Hitori, while grid-shading puzzles such as Nonogram, Nurikabe, Star Battle, Tents and Trees and Shikaku ask you to deduce which cells to fill. Minesweeper, Bridges, Loop Puzzle and Numberlink are about reading clues and connections. Sliding and moving puzzles like the 15 Puzzle, Klotski, Box Pusher and Tower of Hanoi reward planning ahead, and 2048 mixes logic with a little luck. Harder levels need genuinely harder techniques, not just bigger boards, and many puzzles offer a daily edition.
