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.

Rules For Playing 2048

The goal of 2048 is to combine enough tiles to total 2048 before you run out of empty squares. Use your arrow keys to move the tiles left, right, up or down (you can swipe if you are using a mobile device).

The objective of the game is to keep combining like numbers until one tile totals 2048. You will start with a grid of 16 tiles. Two numbers will be given: usually two number twos, or maybe one number four. Move the tiles up or down, left or right, trying to join two equal numbered tiles. When two equal numbers touch, they will add together and become one tile with the sum of the original two.

If you run out of equal numbers on the grid, or you are unable to touch two equal numbers, the game will automatically add another numbered tile to an empty square so you can continue. If there are no empty squares left on the grid, the game will end. By adding numbers together, you will get continually get larger numbers until you (hopefully) can combine two tiles of 1024 to make one tile totaling 2048. Good luck!
