[Hashi] This took me very long and a couple restarts to finally solve it, anyone has good methods?
I recently started playing Hashi and I have been enjoying it. I came across this board (generated by the "Hashi (Bridges)" app on Google Play) and it took me an unusually long time to finish. The methods I use include the following:
- Standard counting neighbours ("3" with only 2 neighbours, "5" with only 3 neighbours etc.)
- On this board right edge near bottom, the "3" has three neighbours: a west "1", south "2", and north "3". If I connect 1-3=2 it would become isolated, so there must be at least 1 bridge to the north neighbour "3". This is similarly applied elsewhere.
- If "4" has three neighbours and only one of them is / practically a "1", then there must be at least one bridge to each of the other two neighbours.
- If there are only two choices for a bridge, I would guess one and see if it works, otherwise backtracks
- Other standard/simple techniques which I don't quite recall
I would like to see if I have missed any crucial methods that may have helped solving this board quicker. Cheers!
