Why are there ads?

We would love to provide everyone an ad-free experience, but we do need to generate revenue to cover at least some of our overhead. We're trying to be as reasonable as possible, and it also allows us to continue to offer you an option to access KenKen puzzles for free. For those who prefer an Ad-Free playing experience, we have an option for just pennies-a-day and it can be canceled anytime. BONUS! KenKen Premium also allows you to Track Your Progress, Join The Leaderboard, Save Puzzles, and more. Please consider this option for the best experience.

In addition, we continue to offer -- pro bono -- our KenKen Classroom Program which provides free KenKen puzzles and lessons to over 1 million students weekly. Revenue we raise from advertisements and subscription sales allow us to keep the program going, plain and simple. So thank you for supporting these teachers and students by supporting us. We all appreciate it.
