Mathdoku and Killer Sudoku for Masters! We made this game for ourselves to play it daily. So we have introduced a lot of tools to skip trivial parts of the both Mathdoku and Killer Sudoku and have fun only with challenging parts. Avoid boring tapping with these unique features: - start the game with smartly filled cells with 'maybes' only with possible digits according to the rules for Mathdoku and Killer Sudoku - long tap cells with 2 or 3 'maybes' to remove trivial 'maybes' in other cells in the same row/column/cage/segment - lazy mode option in settings to automate trivial solutions (be careful, it's for real Masters) Help yourself with hard puzzles using these features: - integrated DigitCalc, a simple calculator that computes all possible combinations of digits in selected cage considering already resolved cells and whether duplicates are allowed. - set checkpoint by long tapping undo button and rewind to it whenever you want - option to sum numbers in cages to help in Killer Sudoku solving - check if solved cells are correct Rules As in Sudoku, for both Mathdoku and Killer Sudoku digits may appear only once in each row and column. But unlike Sudoku, these games also have so-called cages.. Each cage in the first cell has a number and an arithmetic operation. The number should be the result of that arithmetic operation using all the digits inside the cage. E.g. '5+' means that all the digits in that cage add up to 5. The order in which the digits are used in the cage is not relevant. Obviously, in Mathdoku only two-cell cages can have a subtraction or division operation. Mathdoku specifics: - grid size from 4x4 to 9x9 - all four basic arithmetic operations are used - digits can be used more than once per cage Killer Sudoku specifics: - grid size 9x9 only - only sum operation in a cage - no repeating digits inside cage\n - grid is divided into nine 3x3 quadrants for which the same rules apply Detailed help and tutorial are available in the game menu.
