Play a crossover variation of Sudoku and Kakuro! SumSudoku, also known as Killer Sudoku, are addictive logic puzzles best described as a cross between Sudoku and Kakuro. Using pure logic and simple add/subtract calculations, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

Each puzzle consists of a 9x9 Sudoku grid containing areas surrounded by dark borders. The object is to fill all empty squares so that the numbers 1 to 9 appear exactly once in each row, column and 3x3 box, and the sum of the numbers in each area is equal to the clue in the area's top-left corner. In addition, no number may be used in the same area more than once.

The game includes helpful features such as showing possible sum number combinations in an area and pencilmarks to make temporary placement of numbers in the grid.

User reviews

This is very fun and challenging, but it has one major issue. When I choose a number for a square, I don't want the game to automatically remove the smaller numbers in its row or collumn that I placed for notes. That throws me off so much. Please add an option in settings to remove that feature.

I really enjoy the game, but the price for more puzzles is extremely high. If you were to purchase every volume, the total comes out to more than $500. Would love to see a much cheaper option. I could see spending between $10 and $15 for all puzzles, but I don't think it's worth it to buy anything with the current pricing system.
