Test your brain, walk through the maze with the cylinder and insert it in the hole.
Slide a finger towards the desired direction to move the cylinder. Be careful, once started rolling it won't stop until it hits a block or falls down.
New releases will come with facebook integration, more challenging levels, hints for the player, faster graphics, better user interaction and many more...
Have fun!
