The Crown Jewels Crazy Bird Academic Arithmetic

Crazy Bird is a weekly puzzle in Professor Layton and the Unwound Future.

Puzzle[edit | edit source]

This crazy bird has brought one pebble per day back to its nest for 10 days in a row.

It's managed to collect four different colors of pebbles: black, white, red, and blue.

There are half as many white pebbles as black ones. And there are half as many black pebbles as red ones.

How many of each color pebble are there?

Hints[edit | edit source]

Click a Tab to reveal the Hint.

The fact that there are 10 pebbles in total doesn't change.

You know there's at least one of each color, so there are six pebbles left to figure out.

You also know that the quantities of red > black > white pebbles.

Line up the facts and think about them carefully and the answer will come.

Solution[edit | edit source]

Incorrect[edit | edit source]

Too bad!

Where did that bird find those pebbles?

Correct[edit | edit source]


One white.
Two black.
Four red.
Three blue.

What's the bird planning to do with all of those pebbles, anyway?
