KenKen Solver

This is a Silverlight 2.0 solver for New York Times styled KenKen puzzles (http://www.nytimes.com/ref/crosswords/kenken.html).
The new code (0.2 Beta) is hosted on Codeplex here: http://kktools.codeplex.com. But you don't want the code, you want the solver. I figured out how to host it so here it is:


Instructions:
Select a group on the left so it turns yellow.
In the text box, enter the total (for example, the "3" in "3+").
In the drop-down list, select the operand (the "+" in "3+")
Now, click on the cells in the grid to add them to the group.
If you make a mistake, click the cell again to remove it from the group, or select a different group and "paint" over the old group for that cell.

Shortcuts: Ctrl+G creates a new group. Up/Down arrow keys move between groups, and you can type the operand (+,-,*,/ or "space bar") in the text box next to the total instead of selecting it from the drop-down list. That will help when you do an 8x8 puzzle.

Notes: 8x8 solutions may take about a minute. You do not have to fill in every group (try clicking Solve with a blank 4x4 board), but you should expect to wait a long time with an incomplete 6x6 board, possibly forever with an incomplete 8x8 board.
