RULES : Classic Sudoku Rules apply. Additionally,
  • Odd Even Sudoku rules apply ; i.e. grey circles contain odd digits ; grey squares contain even digits;
  • Thermo Sudoku rules apply ; i.e digits along the thermometer will strictly increase from the bulb to the flat end;
  • Arrow Sudoku rules apply ; i.e. the sum of the digits along the path of the arrow must equal the digit in the circled cell. Digits may repeat along an arrow;
  • Killer Sudoku rules apply ; i.e.there are some cages in the grid. The number on the top left corner of each cage is equal to the sum of the numbers in that cage. Numbers do not repeat in a cage;
  • Little Killer Sudoku rules apply ; i.e. the numbers with arrows outside the grid indicate the sum of the digits appearing in the cells in the corresponding direction. Numbers may repeat in the direction of the arrow;           
  • XV Pairs Sudoku rules apply ; i.e. if the sum of digits in orthogonally adjacent cells is 10, then they are separated by an X. If the sum of digits in orthogonally adjacent cells is 5, then they are separated by a V. All possible Xs & Vs are not marked;
  • Kropki Pairs Sudoku rules apply ; i.e. if the absolute difference between two digits in neighboring cells equals 1, then they are separated by a white dot. If the digit in a cell is half or double of the digit in a neighboring cell, then they are separated by a black dot. The dot staying between 1 and 2 can have any of these dots. All possible dots are not marked;
  • Quadruple Sudoku rules apply ; i.e. each small digit inside the grid should appear at least once in the four neighboring cells of the grid;
