So here's where things get a bit confusing.
This set is a mini game of Jenga, but the idea is for you and a friend to try and hit the single block you're given in the pack, three times in a row.
There's a fair number of these sets, and I think the idea is that you collect them all, but the packaging's a bit deceptive.
There is a code included for in-app content, but I have no idea what it includes, and I couldn't find any details online of what you get.
If you want this one and you don't want to go to a store, you'll need to get it on Hasbro's website.
