Welcome to this new Killer Solver
I have been solving and making Killer Sudoku puzzles since 2005 and although my Sudoku solver has been
part of this site since those early days I have not attempted a public solver until now. The main reason
I have shied away from attempting it was the complexity of the puzzle in terms of the user interface. However,
I hope I have now come up with a satisfactory solution. The independent 'Designer' handles the entering of the
clues and cages. Keeping this separate and being able to (loosely) validate the entry should allow puzzle solvers

required to transport a Killer using a web address is a little too large. The puzzle requires the clues, the
cages and the state of the board during play. So I haven't thought of an easy method to provide those features.
- I will be adding a Solution Count soon.
- Much of the Killer strategy text that is displayed in the result panel is a little too obscure.
I will be making more friendly versions in the next upgrade.
