Wei-Hwa's Puzzle Challenge Number 7 by Google

July 07, 2006: US States Jigsaw Sudoku: My friend and current U. S. Puzzle Champion Thomas Snyder sent along this amazing variant where the region shapes might seem familiar to American cartographers. (Note to Sudoku researchers: This puzzle is not Sledgehammer-complete!)

Drag symbols from the palette on the left into the grid to place them. You'll be warned (in red) if you're trying to place the same letter in the same row, column, or region. You'll know you've solved it when all the lights turn green

Hints:
Solve your basic Soduku puzzle with a little twist. For me, 5's were the easiest to place.
