I love to play Killer Sudoku, also known as Sum Sudoku. If you are familiar with Kakuro, it is a cross between Sudoku and Kakuro, and gives sums of squares as the hints.

There is a website Killer Sudoku Online where you can play Killer Sudoku. The game is written in HTML, but it did not work on my Pre under WebOS 1.3 and before.

With WebOS 1.4 the website works on my Pre exactly as it does on my laptop. Whatever Palm fixed, thanks!
