The Kenerator
Automatic Puzzle Producer
Mr. Miyamoto is a totally nice guy. But, as KENKEN grew, he was slightly hesitant to keep creating millions of new puzzles by hand, every day of the year, all by himself. (It would definitely cut into his scuba-diving time.) So the Kenerator was born: a complex artificial-intelligence computer program that generates and checks every new puzzle. The Kenerator was designed with the oversight and according to the specifications of Mr. Miyamoto, working side-by-side with leading artificial-intelligence expert David Levy.
The Kenerator instantly verifies that each “cage” is correct, that no number appears more than once in a row or column, and most importantly, that each KENKEN puzzle has only one solution.
The Kenerator also assesses the relative difficulty level of each puzzle: easiest, easy, medium, or hard. This process is the result of a personalized algorithm based on a wide variety of factors.
And you thought we just picked the numbers out of a hat, didn’t you?
