Why start with puzzles?
Puzzle games have simple rules, fast onboarding, and easy stop-and-go play — perfect for commutes and breaks, and many parents see them as safe for kids. Our Puzzle category includes Sudoku, 2048, Minesweeper, sliding puzzles, Sokoban, Klotski, match-3 and Mahjong.
Beginner picks: 2048 and Sudoku

Minesweeper deduces mine locations from numbers — classic brain training. Mahjong tests eyes and reaction: match identical tiles to clear the board.
Spatial & strategy: Sokoban and Klotski
Sokoban pushes boxes to targets in minimal moves — all about planning. Klotski is a century-old sliding puzzle: free the key block within limited space.
