Roll the Ball is one of the most addictive free puzzle apps on the market, and the goal of the game is quite simple. All you have to do is rearrange a board filled with tiles such that the tiles create a single, unbroken path for a ball to travel along as it goes from point A to B. The game works by having the player move one tile at a time on the board using a single free space as a hub for change. The goal is to finish the puzzle with the fewest number of moves.

This game has more than 300 levels in a range of difficulty settings. The settings include beginner, intermediate, hard, advanced, and extreme. There are 60 puzzles in each mode, and you can only get all three stars on each puzzle if you solve the puzzles in the allotted number of moves.

The controls for the game are quire straightforward. You move tiles by sliding them with your finger. You can only move a tile to the empty position, and you can only move tiles that are directly adjacent to that position. It is possible that you could create a situation where a puzzle becomes unsolvable, but the game will automatically release the ball after a certain amount of time and force you to restart the level if you fail.
