SuDoku
Also commonly spelled Su Doku and Sudoku, this is a number placement puzzle game that is similar to, but slightly different than, the Number Place puzzles found in Dell puzzle books. It is a paper and pencil logic puzzle (not a math puzzle), but it can be played online, where you fill in a 9x9 grid with the digits 1 through 9 following certain very easy rules that account for the numbers already pre-entered into the grid. Puzzle difficulty depends on the starting numbers provided. Variations of the game have been around for some time, however it is now experiencing an extraordinary explosion in popularity and "addicts" around the world. It is frequently called the Rubik's Cube of the 21st century.

USA Today: SuDoku Classic
July 11, 2005. USA launches SoDoku in their newspaper. Plus they got it right! The puzzle is graded for difficulty, the puzzle is big enough for notes, and it is true SuDoku with symmetry in the provided numbers! Their online version includes a number of interesting features and can be printed out along with the solution. Kudos on every point, although it would be nice with the online version if they didn't print the solution on the same page as the puzzle itself. SuDoku Classic includes an archive of recently published puzzles.
