Sudoku Killer

A 9x9 grid fills the screen. In Sudoku Killer, standard row, column, and 3x3 box rules stay in place, yet extra cage totals add another layer of number logic. Digits from 1 through 9 must occupy all 81 cells with no repeats inside any row, column, or mini-square. Small grouped areas also carry a target sum, and the numbers inside them may appear in any order. That extra arithmetic often gives away placements that would stay uncertain in a regular Sudoku puzzle.

How to play?

Choose from Easy, Medium, Hard, Expert, or Insane before the grid loads. The difference between those modes comes from the number of preset digits on the board. More filled cells leave fewer blanks to solve. Fewer clues leave more empty spaces to work through. Fill missing numbers by checking what already sits inside each 3x3 section, then place digits that fit the remaining row and column rules. Use the printed cage totals to narrow down number combinations through addition and subtraction until the whole square is complete.
