Not applet capable!

Sudoku

1. "Pick an old puzzle" displays one of five internal puzzles. "Next old puzzle" then cycles through the other internal puzzles. Fill in as many blank cells as desired. Pressing <Enter> will evaluate all non-blank cells, and append an 'x' after each incorrect guess.

2. "Enter a new puzzle" allows the user to input a puzzle from some external source. When the button is pressed, the answer is computed, and all non-blank cells are "grayed out". Fill in as many blank cells as desired. Use the <Enter> key or the "Evaluate input" button to check your current guesses.

3. Use the Web browser's "refresh" button to return the applet to its initial state.
