Hints

Click a Tab to reveal the Hint.

US Version

It wouldn't be a tough puzzle if all you had to do was simply swap them. First just try moving things around, then when you can't move any more, think about how many more steps would have been required.

UK Version

The four bars between A and B are what make this a tough puzzle.

Start by moving things around until you get stuck. Then think about how many more steps would have been required.

US Version

You'll definitely run out of moves if you keep switching between moving A and B. At some point, you're going to need to swap A and B in one fell swoop.

UK Version

You'll definitely run out of moves if you keep moving A and B alternatively.
At some point, you're going to need to swap A and B in one fell swoop.

US Version

It doesn't matter if you start with A or B, but here are the instructions for A: slide the second block from the top over to the left, and move A down to the right of the third block. Then move the second block all the way to the right, and slide the third block up and to the left or it. The rest is up to you!

UK Version

It doesn't matter whether you start with A or B, but here are the instructions for A:

Slide the second bar from the top over to the left and move A down to the right of the third bar. Then move the second bar all the way to the right and slide the third bar up and to the left of it.

US Version

Continuing on from Hint Three, move B to the left side of the row that A is in. You can now move A into its target slot. All that's left is to use the last four moves to get B into its target slot.

You can do it!
