In case you have not noticed recently I am sort of hooked on puzzle games particularly sokoban games. Spice just released a free Sokoban game that promises to bring the classic Sokoban puzzle experience to the PlayBook. This Sokoban game has you are moving the boxes around the maze to get them in the right location. It has 100 built in levels for you to test your skills and enjoy.
Sokoban is available free in App World for a range of BlackBerry smartphones.
