In slide puzzles such as this one, if you move things around without a clear idea of what you'll move next, you'll ned up back where you started before you know it.
Move the pieces so that you are constantly forming new configurations for the pieces.
To complete this puzzle, you'll need to utilize the space in the corridor connecting the two columns of balls.
For example, you could try moving the red ball that's third from the top into the small pocket above the middle square of the corridor. Then move two blue balls all the way over so that one occupies the space the red ball formerly sat in. Move the red ball out of the corridor into the blue balls' column in the spot second from the top.
While it may seem counterintuitive, you need to move some balls back out of the correct field to solve this puzzle.
As detailed in Hint One, move two balls to the opposite side, move the ball hidden in the small central pocket over to the space created, then move two balls over the other way. Repeat, and see what develops.
Solution
Correct
Good job.
This puzzle can be completed in 30 moves. Does that make you want to retry it?
