*edit* if you have a version other than 6.22 your memo with the symbols may look different. If you don't understand how to solve than describe your memo to me and I'll give you the answer. *edit #2* I've kind of died on deviantart recently. I may not answer any questions you have fast enough. Please look through the comments and see if I've already answered your question. Thanks C: edit #3: Some people are confused on what it means to flip the number upside down. 1 upside down is 1, 2 upside down is 2, 3 and 4 cannot be turned upside down and still be a number, 5 upside down is 5, 6 upside down is 9, 7 cannot be turned upside down, 8 upside down is 8 and 9 upside down is 6.
-------------------------------------------------------------------------------------------------------------------------------------------------------- And if you'd rather just find the answer instead of understand the puzzle, here's a list of the ones I know of...
941: 1416, 9146
176: 1971
679: 6799
239: 6395, 6392
915: 2156, 5156, 9516
Pretty sure there are more than this, but this'll do for now.
I understand the puzzle, but the combo never works, Ive tried several play throughs and the answer never works. My number now is 915, so the answer should be 2-1-5-6 right???
I got the key!
