Kakuro Puzzles

I've always been a fanatic of puzzles and riddles, and eventually that led me to discover Kakuro. I enjoy Kakuro due to the mathematical and logical synergetic nature. I also enjoy the sense of superiority when I compare it to a popular yet very simple puzzle, Sudoku ... which Mindona does. ;D

This is an example of an easy Kakuro puzzle. The objective is to saturate the grid with the numbers 1-9 while making certain that you do not use the same number twice in a given row or column and that all the numbers within a given row or column add up to the given total. Now look at the upper left where you see two rows both with three square. The only way to fit three integers into six is by using the smallest available (1, 2, 3) and to fit three in seven you substitute the three for a four (1, 2, 4). Next, we'll look at the column that calls for two numbers that add up to 4, which will be 1 and 3. Seeing as 7 cannot host a 3, we can tell that a 1 will go in the top box and a 3 will go in the bottom box. Rinse and repeat until solved.

While ones like these are excellent for beginners, do not fear that the difficulty caps off here. There are many puzzles which will require you to look numerous steps ahead in order to deduce which numbers should go where.

I generally do these while eating breakfast and during any periods in which I find myself doing nothing else productive ... such as waiting for Mindona to finish up in the locker room. ;P
