To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I purchased this as a gift for a family with 10-12-14 year old kids. Read the instructions when I received it and almost returned the game because it sounded so dumb and boring. (It is very similar to the card game War.) Players flip cards onto a pile in turn. When a card which says "Smack It" is played, the first to smack takes the deck. The cards have numbers on them, which are relevant only if the previous card said "challenge": high card takes the pile. The 10 year old loved it and played repeatedly with her grandparents, mom and aunt. The 12 and 14 year olds were involved with other things, so I didn't get their reaction. Easy game to play, fairly quick to complete ( a big plus in my book).
