Puzzle Location: Grand entrance hall

Here we have some mysterious shells.

When you close and reopen them, the number of pearls they contain doubles.

The maximum number of pearls each shell can hold is eight, and the shells cannot shut if they have five or more pearls inside.

Can you make each shell contain five pearls?

Touch the button above a shell to double the number of pearls it contains.

It's possible to move one pearl at a time from one shell to another by sliding it.

Hint 1

You need fifteen pearls in total, but there is no way to reduce their number, so be careful not to create too many of them.

If you want to solve this in as few moves as possible, you should try to avoid moving single pearls.

Hint 2

There is more than one solution to this puzzle, but let's take one example.

First, increase the number of pearls so that each shell contains four.

Hint 3

Continuing on from hint two...

When each shell contains four pearls, move one pearl to another shell so that one shell contains three pearls and one shell contains five pearls.

Super Hint

Continuing on from hint three...

Take the shell that contains three pearls and double their number to six.

Then move a pearl from there so that all of the shells contain five pearls each.
