Normal sudoku rules apply. Beige lines are "hit point lines": Counting the diamond as position one, digits in their correct position must sum to the number in the diamond (eg a line who's diamond was the value 9 may be made up 93145 as 4&5 are in the 4th and 5th position and sum to 9 fulfilling the diamonds requirements). Digits may not repeat along a line (the digit in the diamond is considered on the line and may not appear elsewhere along its line). Digits in the diamonds also count how many different lines they appear on, including themselves (eg if a diamond contained the number 3 it would appear, in any position, on two more lines). Digits which don't appear in a diamond have no limitations as to how many lines they appear on.
