Puzzle

US Version

On the top row of the picture shown below, you have three cups of juice followed by three empty cups. Your objective is to change things around so that the cups are arranged as shown in the bottom row of the picture.

Assuming you can only move one cup at a time and that all rearrangement has to be done by hand, how many cups will you have to pick up?

UK Version

On the top row of the picture shown below, you have three glasses of juice followed by three empty glasses. Your objective is to change things around so that the glasses are arranged as shown in the bottom row of the picture.

Assuming you can only move one glass at a time, that the glass can't be put down again anywhere other than on the shelf, and that all rearranging has to be done by hand, how many glasses will you have to pick up?

Hints

Click a Tab to reveal the Hint.

If it weren't against the rules for this puzzle, it would be easy to just switch the second and fourth glasses with each other.

But since you can only pick up one glass at a time, that idea is right out.

You have to move things around so that there is juice in every other glass. Surely there's a way to do this that doesn't involve switching the glasses themselves around.

You don't need to change the positions of the actual cups. You can achieve the same goal by just moving the liquid from one cup to another.

If you are just moving liquid, how many cups do you need to pick up to complete the puzzle?


Solution

Incorrect

Nope!

Think about how many cups you really need to move to finish your task.

Correct

That's right!

US Version

Pour the contents of the second cup into the fourth cup and then return it to its original position as shown above. This way, the task set before you can be completed in one move.

UK Version

Pour the contents of the second glass into the fourth glass and then return it to its original position as shown above. This way, the puzzle can be completed in one move.
