PacSci-Doku: "Quickly Disappearing"

By Dennis Schatz - Senior Vice President for Strategic Programs

Looking for the "Last Chance" edition?


Do you Sudoku? It's one of the hottest number games around! Well, here's a twist we think you'll love. We call it PacSci-Doku, can you guess why? Here's how it works. Instead of filling in the blanks with numbers, use letters. Hidden in one of the columns or rows is the answer to a science question. The question in this edition is:

What has shrunk by more than 20% in the last 30 years?

To find the answer, complete this PacSci-Doku using the following nine letters:

A  O  E  _  I  R  C  P  L

Each row and column in the grid below has to have only one of each of these letters. Each of the 3 x 3 mini-squares in the 9 x 9 square also needs to have only one of each letter.
