Ha ha, yes! This does solve with basics. Any ideas why this fooled the Draw/Play function? Could it have been the empty boxes 1 and 9? Curious. |

I was wondering the same thing! I used to think that the puzzles on this site that were improperly rated as VH were probably because the software was coded to first look for some VH moves before considering all other basic moves - BUT today I started wondering if there are maybe certain basic moves that are not being found at all (and consequently rating this puzzle as 'too hard!'). I came to the conclusion that it must not be finding some naked triples (or maybe some naked singles?) under certain circumstances. Interesting! |

Very good analogy dongrave. That must be what is happening here. Funny it didn't assess it as Very Hard in it's rating, as you mentioned, and which we have seen at times. Went to the next level of Too Hard.

It WAS a pretty neat puzzle, and it did take a bit more digging with those basics in mind. Had me going for a while, too. |
