#651 - populated cells = 24 = 29,6%
basics: G9=1; H9=5; J7=6; B7=J4=8
populated cells = 29 = 35,8%
strategy: try to get hidden pairs or triplets. No solver used.
combinations of D3 = (3,6,7,8) and D8 = (1,2,3,7) as numbers 1,6,7,8 are populated most.
D3/D8 = (3/2) solves.

Review:
D8=2 solves.

# 651 C7=8 D8=3 G9=1 H9=5 J4=8 J7=6 Basics to 29

1. Number 1 n=5 e=4 N=10 Nc=5 Ns=23 => D6=1 solve

2. Number 4 n=2 e=7 N=26 Nc=20 Ns=15 => B2=H8=4 solve
Note : C5=F7=4

3. Number 5 n=3 e=6 N=24 Nc=19 Ns=16 => B6=E2=5 solve
Note : A3=5
