I don't mean to thread-jack, but as there are other people who think this is too confusing I want to share something I found recently.  There's a new game that you can play with Bitcoin (or Litecoin, Dogecoin, Earthcoin, or just for free) called SatoshiGem.  It's a LOT easier to understand and play than Blockchain-Reaction(it's basically candy crush).

There's multiplayer pvp and tournaments, and the only problem with this site right now is that there aren't enough people.  Let's change that!

The website is www.satoshigem.com and the forum post is at https://bitcointalk.org/index.php?topic=555362.msg6062104#msg6062104
