Very interesting to see how only one digit can change difficulty !

The last pair looks very impressing, however the 11.8 can be solved immediately with the easy-to-spot TH (149) move r7c6=3.

This one is less yielding:

Code: Select all

........1.....2.34..4.1356...2.....3.3..562..7.8.3.....1.3.542..2..64.15.4.1..3.6  ED=1.5/1.2/1.2
........1.....2.34..4.1356...2.....3.3..56...7.8.3.....1.3.542..2..64.15.4.12.3.6  ED=11.8/2.0/2.0

Not really, TH (or tridagon) 789 (b2389) -> 2r3c9, then singles.
But i would not like to solve the 10.2 puzzle above manually ...
