Hey everyone, for anyone who has done the Part Five for this assignment which 3x3 square did you start with that you thought was easiest to finish the puzzle with? (having a little bit of trouble solving it.)

Hey everyone, for anyone who has done the Part Five for this assignment which 3x3 square did you start with that you thought was easiest to finish the puzzle with? (having a little bit of trouble solving it.)

For things like this, i start with the corners and make notes about what numbers could go in each square. For example, in the top left corner, there is a 2-square section that adds up to 4, so you know that 1 and 3 must be in those squares, so no other squares in that top 3x3 section or that column! That means that the 2-square section in that 3x3 can only be 2 and 4. There is another 2-square section in the bottom right corner so that also must contain 1 and 3. Hope that helps!

I also found it helpful to do more research on the puzzle type outside of what what taught in the lesson.
For example, if a 2-cage has a total of 3, 4, 16, or 17 there is only one combination of values that can be used. (3=2+1, 4=3+1, 16=9+7, and 17=9+8.) 3-cages with only 1 combination are: 6=1+2+3, 7=1+2+4, 23=9+8+6, 24=9+8+7.
Just keep at it, it’s so satisfying once you get it

Sodokus are my favorite - but this is the first time I’ve ran across this kind!
