I have been a huge fan of BerryBlow’s Labyrinth game for BlackBerry smartphones for years but there have not been many similar games. Jerry pointed out to me Mobile Reason has a game called A Maze Ninja! that was released last year with similar gameplay. It offers up 30 levels of accelerometer controlled puzzle play with you guiding your ball around the maze. They promise in the description to add 50 more levels but it has been awhile since the game has been updated.
You can find A Maze Ninja! for $1.99 in App World.
NOTE: Since the game uses the accelerometer it only works on devices that have one which is most of the BlackBerry 7 devices, Storm series, and Torch series devices.
