Distribution of start numbers

This table shows the spread of puzzles mapped to the numbers a puzzle start with. Clicking on the number will give you a random puzzle with that start number count. I've put a sum-line at 30 since some people think a real sudoku should have less than or equal to 30 start numbers.
