Like Sspent, at first, couldn't even see a route. Then I tried to identify what is possible at all just by watching the board and suddenly I spotted a plausible route... It was the winning one. Big fun.
Very nice. Like hi19 the 68s clicked pretty early on but it took quite a bit of careful thinking about what actually I was trying to do to get the 62. No accidentally stumbling upon the solution for this one!
