Kakuro++ Cross Sums Puzzles

More than 3800 grids of the best puzzle-game available.
Kakuro (also called Kakkuro, kakro, cross sums or カックロ), is a logic game that consists of filling in a grid of numbers, in the same way as a crossword puzzle. If you enjoyed Sudoku logic, you'll love Kakuro's puzzles
As with Sudoku, the rules of Kakuro are simple and can be learned in a few minutes. All you need to do is make simple additions to put your logic to the test.
Kakuro Plus offers 15 different game levels and 200 puzzles per level: It will probably take you more than a couple of hundred hours, and a lot of logic to get these 2800 puzzles finished.
As with Sudoku or crosswords, each puzzle has a unique solution. It is up to you to find it using your logic and perspicacity.
This version of Kakuro ++ allows you :
• To access all the 2800 Kakuro puzzles.
• To begin and progress, some puzzles have been specially designed for beginners. Their small size and difficulty levels is suitable for first-time players.
• To access grids of any level. The 15 game levels provide a smooth progression, from beginner to logic expert.
• Annotate the table, to record assumptions and move forward in complicated cases.
• To go back: there is a "UNDO" button to cancel up to 100 actions. Don't be afraid to test your assumptions anymore.
• To enjoy high definition graphics for maximum readability.
This version of Kakuro ++ adds unique features:
• An automatic deletion of unnecessary assumptions, when one of them is no longer logical.
• A help system, which offers you several possibilities:
• Check if your grid has errors, without showing them to you. This allows you to remove a doubt, without providing you with the solution.
• Show you where the mistakes are.
• Give you a hint, which will allow you to move forward in difficult cases.
• A visualization of all possible combinations of a clue. A color set shows you the possible logical values.
The Kakuro rules:
• Your goal is to fill in the grid with numbers from 1 to 9 like a crossword puzzle.
• The clues tell you the amount to be reached in each group of horizontal or vertical boxes.
• As with Sudoku or crosswords, you will win when the game board is fully filled, without any mistakes.
