Normal Sudoku rules apply.
Olive green thin lines are Mod 13 sum lines - the sum of the digits of the cells the line passes through is a muliple of 13. Digits of cells where the line is only along the cell's edge are not included in the line's sum.
Where an olive green line crosses 3x3 box borders, digits in the cells either side of the border sum to a multiple of 7.
Yellow circles are Doubles or Quadruples and every digit in the circle must be assigned to one of its surrounding cells inside the sudoku grid.
Cells joined by an X must sum to 10. Not all Xs are given.
Cells joined by a white dot are consecutive. Not all dots are given.
