Sure, the puzzle looks a little daunting at first, but take heart. If you use the five open spaces in the box, you can solve the puzzle.

Think about how to move things around so that you create some wiggle room for the bigger blocks.

The solution requires that you move that big yellow block into the upper-right portion of the screen. Here's what you can do to start making room for that move to take place.

Move the blue block at the bottom over to the right and slide the purple block into the space that has a hole. From here, if you move the blue block at the bottom so that it sits directly beneath the yellow block, you'll free up a space on the right that you can work with.

This hint starts from where Hint Two left off. Move the purple block into the lower-right space and then bring down the green block above it. Next, move the purple block in the upper right as far to the right as you can and move the blue block in the upper left to the far left. Now you should be able to move that big yellow block up and to the right. With that block out of the way, the rest should be easy.
