Meh. They have one of these in the paper every day. I used to do them but after enough times when my results got more than the answers published the next day, it just got tiresome. Either that or they included words which were either proper nouns or couldn’t be found in any dictionary.
There’s no consistent set of rules. Does it follow a standard Scrabble Dictionary wordlist or doesn’t it? Too annoying.
Sorry to be a buzzkill but that’s just my honest reaction.
