Today’s puzzle is not the ordinary 3×3 Killer Sudoku, but rather it’s a 4×2 variant.
All rules remain the same, except that there are now only 8 digits used (1-8).
NOTE:Since only 8 digits are used, the sum of all boxes, rows and columns is 36! Be careful when you look for “innies” and “outies”!
Let me know what do you think of these…
I enjoyed the 4×2, although found it substantially easier than the usual 3×3’s. I think it may be because there are more possibilities for using the 36 sums, since 4×2 and 3×3 shapes both have the same perimeters.
FYI — some of those 3×3’s you’ve done have been awesome! The diagonal one (which, to be fair, I didn’t realize was a diagonal) was amazing. Keep up the good work!
