I've been using this method all the time but I have a 20x20 that doesnt have a number greater than 10 and doesnt have individual numbers that add up to 20 with spaces included, any tips?
Try looking for a group with small numbers and one larger number ( like 2, 3, 7). Put the small numbers in temporarily. If the large number is more than half of the remaining open spaces, you can find where some things go. ( So 2 space 3 space uses 7 spaces. 20 minus 7 equals 13. Seven is more than half of 13, so you can find where one place must be filled. I hope this helps. Good luck and have fun.
This was made SO much more difficult than it needed to be! So many opportunities for fills when the commentary was “that doesn’t help me at all”… when it 100% did.
