Previous Puzzle:- Kyudoku :- Introduction
There will be numbers in a grid. You just have to circle nine unique numbers (1 to 9) such that each row and column has sum of 9 or less. In some puzzles, one or more circled numbers may already be given.
Here is today's puzzle.
Note that this puzzle will be unsolvable. However, if you interchange 2 digits by their positions, the puzzle can uniquely be solved. Can you find how to solve this puzzle?
Note:- There is some brainwork you might have to do. You have to interchange 2 digits, such that the solution becomes unique. There may be a case when you interchange 2 digits and you found solutions, but the solution is not unique in that case.
Bonus:- There is an Easter Egg hidden in the puzzle. Can you find it? (Check the Title first) . Bonus:- There is a shaded box in the figure. Can you guess what number it can take?
Edit: @Smartest1here has provided a solution which contradicts mine, but his/her solution perfectly works. That, of course, does not make the puzzle unique, but I want a direct logical path from him/her to get to the solution. My solution, has a direct logical path. Also what I have in mind is 2 solutions, which also, is a problem =) .
Edit: I thought this puzzle would be interesting, so right now I am not concerned with uniqueness, as there are 3 solutions I found for now, 1 found by @Smartest1here. There are 2 more solutions I have in mind, the puzzle is still open for now.
