The numbers 1 to 9 are to be placed once in every row, column, long diagonal, 3x3 grid and irregular shape (or cage). From the given starters can you complete the puzzle?

I had found this pretty easy going for a while, but I shortly got stuck and for the life of me I couldn't make any further progress. I even entered it into a Sudoku solver and it said no further information was able to be obtained without random guessing, and I was sure that the additional information didn't come from the colored regions since I had carefully checked and rechecked that no further information could be obtained that way from the current state I had.

However, Josie, after reading your latest comment to FK I realized that long Diagonals were restricted too! After seeing that, everything else followed easily.

Thanks for the great puzzle!
