Spiral Stumper Series is a $5$-puzzles series taken from the Final Round of a local (national) contest, KPK, which has been ended recently and authored by me. The theme is spiral and each puzzle is standalone (there will be no meta, etc.)
Study the 2 examples given on the left and solve the puzzle on the right!
The solution for each puzzle can be uniquely determined.
