Sokoban is a free puzzle game for Android, developed by Daniel Musil. It is a classic computer puzzle game where the player's goal is to push boxes to storage locations. However, it is not as easy as it sounds, as the player cannot pull boxes nor walk over them. The game offers 1000 Sokoban levels, all accessible for free, which equals to hundreds of hours of fun.

The game has different difficulty levels ranging from lite to very hard. The solutions to most puzzles are also available to help the player with hard ones. The game has an intuitive swipe control system, but the player can also use keyboard keys to push the box. The interface is simple and clean, free of unnecessary distractions. All levels are accessible from the beginning, and the undo system is available to withdraw wrong moves, which is useful for Sokoban newbies. The game also supports HD screens, and all levels are proved to be solvable.

Overall, Sokoban is a great game for puzzle lovers. It offers a lot of levels and difficulty options, making it suitable for both beginners and advanced players. The availability of solutions to puzzles is also a big plus. However, the game has no option for feedback or suggestions within the app, and the player has to contact the developer directly via email.
