SumSudoku: Killer Sudoku 2.8

SumSudoku, also known as Killer Sudoku, is an addictive logic puzzle that combines elements of Sudoku and Kakuro. It provides endless entertainment and intellectual challenge for puzzle enthusiasts of all ages and skill levels.

Each puzzle consists of a 9x9 grid, with certain areas outlined by dark borders. The goal is to fill in the empty squares so that the numbers 1 to 9 appear exactly once in each row, column, and 3x3 box. Additionally, the sum of the numbers in each outlined area must equal the clue provided in the top-left corner of that area. No number can be used more than once within a single outlined area.

The game includes helpful features such as displaying possible sum combinations for each outlined area, as well as the ability to add temporary notations on the grid. A gallery view option allows players to track their progress visually on a larger scale.

For added enjoyment, Conceptis SumSudoku offers a weekly bonus section with an additional free puzzle.
