PUZZLES

Ken Ken? Yes you can can!

If you are a Sudoku fan, welcome to your new addiction.

Today's print edition introduces a daily number puzzle, Ken Ken, created by Japanese educator Tetsuya Miyamoto as a way to teach his students math concepts.

The name translates to “;cleverness squared,”; and like Sudoku the puzzle involves filling in a grid of squares with numerals. The difference is that some of those numbers are determined through math equations.

For example: Two squares are grouped together with the notation “;3-”; in the top left. This means the two numbers in the squares must total 3 if one is subtracted from the other.
