It is seldom to find
4.8(UR,UL)
4.9(UR,UL)
6.0(BUG)
8.1(Nishio/Region/Cell ForcingChain)
8.7(Region/Cell/Dynamic ForcingChain)
with there's no clues can be take out.
Eventhough these puzzles are less than 11.0+.
If there is found, I will add in this thread.
When there are more than 50 puzzle, the work of that rating end.
