This game owns bones and the negative reviewers wish it was something much less artfully crafted.
As others have stated, the categories are intentionally misleading and difficult to put together on purpose because if they weren't there wouldn't be a game to review.
The key to not being misled is to put together more than one category at a time. Or you can rush ahead and burn all of your guesses and text "CONNECTIONS WAY 2 HARD AGAIN >:(..." to your wife like me.
It's a rewarding pastime and I have a lot of respect for its diabolical puzzlemasters.
PS - Remember when the category for the day was "vegetable name minus one letter"? I remember, and I will never forgive you.
