Rule of six says that 6-neighbourg nodes are safe.
In your case you have 1.2.3 nodes on the top,
4.5.6 nodes in the middle,
7.8.9 nodes in the bottom,
and 10,11 off-screen nodes in the bottom.
Node 3 is a baddy
Node 5 is surrounded by 6 nodes so safe
Node 8 is also surrounded by 6 nodes so also safe.
This screen does not disproof that rule.
