Does anyone have any idea what the broken bridges/Spurs on the 1,2,3, and 4 bolded nodes are supposed to convey?
The number 2 node has 3 of them which is confusing since it only can have 2 connections, which suggests these spurs can’t be connected to anything.
I can’t tell if they are fixed starting points, non-connectable points, or something that will help form the solution and should be ignored while solving the grid.
Thanks!
