Your Top Two Reasons To Avoid Work: Mastersoft SuDoku & Kakuro Reviewed!

Posted by Jon Westfall in "SOFTWARE" @ 08:00 AM


That Wasn't Too Bad, How About Kakuro?
We'll start with an Simple Kakuro. You'll notice in the image below that only some of the board is used, this is to keep us sane as we learn ;). The margins show us what each row and column are supposed to add up to. A number in the upper right indicates row total, a number in the lower left indicates column total.


Figure 6: This really isn't as scary as it looks!

Let's look at the last column, the one we know has to add up to 9. What values could go there? Well, the first row has to add up to 16. We could make 9 with 8 + 1, but then the other value next to the 16 would have to be an 8, making 2 of the same value in that row - a no-no! Let's try 7 & 2, making the first row 7 & 9. I'll add in a flag in case we have to roll back with the yarn-ball feature!


Figure 7: Ah, flags. Multi-colored even. If you set a flag, by clicking Yarn-ball you'll see a slider with your flags in place, making it easy to roll back.

Ok, now we know that the next row has to add up to 9, and the first column has to add up to 3. What, plus a low number, and plus 2 might make 9. Given that the second column has to add up to 23, perhaps we should think of a high number. Maybe 1 + 6 + 2. We'll try that approach.


Figure 8: Oooh... we're getting close to knowing if we've done well or screwed up. We could always use the calculator in Windows Mobile if we need help with a quick calculation!

Ok, now we have one value left. The question is, can we find a value that is true for both of these problems: 9 + 6 + ? = 23, and 2 + ? = 10. YES = 8! So we enter 8 and get the glory & prizes


Figure 9: Winners we are!

Ah, alas, I'm struggling (maybe that's because I just re-installed the release version from the beta... ;) ). Now that wasn't too bad, and I feel like I've had a great mental exercise!
