I'm a big fan of sudoku but I've been finding the puzzles a bit too easy lately so I was pleased when kakuro started appearing in the papers! But now I've gone from one extreme to the other and find kakuro quite difficult - trying to add up different number combinations in my head! Which is why I've brought Infinite Kakuro to play on my computer - it's a complete godsend! If you start off with the easy puzzles, some of the numbers are already filled in for you, and it highlights when you've entered a wrong number, as well as all the possible number combinations - you can turn of the help once you get going. Being able to add your own pencil marks is also really handy to help you remember what could go where.
As you get better, you can move up the difficulty levels - I'm only on medium at the minute - but with an unlimited amount of different puzzles I know I can play as much as I like on each level.
And if you're still trying to complete the kakuro puzzles in the paper, you can type the numbers into the puzzle solver and let the software solve it for you - awesome!
I definitely recommended this game to all sudoku fans and anyone else who wants to challenge their logic skills!
