Created by Japanese math teacher Tetsuya Miyamoto in 2004, Kashikoku naru Puzzle translates literally as "A Puzzle That Makes You Smart". Hitting that exact right combination of mathematical calculation and logical reasoning, it soon became an international sensation under the name KenKen.

At JayIsGames, we're always on the lookout for good online versions of pen-and-paper games, and Nextoy has provided with 6 daily, devious, and easily-printable KenKen. Why? Because they Ken Ken Ken!

A gorgeous puzzle game with an impeccable user interface, Minim sets the standard for browser-based casual games.

Zerosum is an intense variation on match-3 puzzles, with strict policies on winning and losing but vast opportunities for strategy. Easy to learn, hard to master.

As more bricks rise from the bottom of the screen, you must frantically add them together to keep the stack from reaching the top. It's more puzzle gaming enjoyment than I've had in a very long time, and the pacing is perfect to keep you motivated but not frustrate you.
