If you're persistent in your efforts, you'll eventually get the ball to the hole, but there are tricks to streamline the process.
The large block in the puzzle is relatively limited in range of movement, so you're going to have to do more work with the smaller and more maneuverable blocks. If you focus on them and plan out a route, things should go smoothly.
If you move the green block on the right down, you can fill the space you create with a purple block from the right. If you can pull that off, you'll be able to move the blue block in the upper left, which will allow you to move the red ball out of its slot.
It may seem complicated, but give it a try.
There is no set solution to this problem.
Here's one way to start out. Move the lower-left purple blocks, then slide the lower blue block to the left. Next, drop the green block on the right down.
The rest is up to you.
Solution
Correct
Well done!
Were you able to get the ball to the hole without shuffling too much back and forth?
If you had to move the ball lots of times to reach the goal, don't worry! Figuring out how to get to the goal in the fewest moves possible is an interesting puzzle in itself.
