Early Coloring on funster Extreme 32


This post tries for a quick victory on Funx 32 with coloring, without the usual bv scan and X-panel preliminaries. That appears to flop, until three remote pair chains are connected into a long XY chain to wrap two clusters.

The Funx 32 staggers out of bypass alley with little reason to hold on, and not many candidates to dress up the wounds. Here’s the bypass trace, in case you’d want to compare basic notes.

One grid tells the story. There are three almost remote pairs, with bv values 17, 78, and 57. No two combine in a coloring cluster, but two XY chains on 78 and 57, the almost remote pairs, connect in c3, wrapping orange in the red/orange cluster.

Red 7r4c1 removes 7r1c1, expanding blue/green, while 7r5c4 confirms S7 and wraps green.  Red and Blue carry the day.
