Actually, I've been playing this and I like it. The problem is, as with all F2P games, you only have so much energy before you must buy more. I can't seem to keep any coins or gems because I don't want to stop playing and I spend them almost as soon as I get them. I'm sure it gets easier as you get to the higher levels and receive more energy. The good thing is that it forces me to quit and go on to other things (ie dishes, cleaning, writing etc.)
It's mostly HOG's with some find the differences and there's a journalist that asks questions (if you choose.)The answers are in a hangman form, but difficult. The only way to find them is in the BF forum.
There are also humorous escapees which you capture once you find the right tool.
You can use your gems to purchase outfits for your avatar (mine is still running around in her undies!) and furniture for the office. All of these items give you boosts in percentages of coins received, energy fills faster or experiences fill faster.
As in all F2P games, you must have patience unless you spend a lot of real money to purchase coins and gems.
Some in the forum have downloaded several (F2P) and play each until they run out of energy. The energy refills even if you are not playing them, so you can return to them later in the day with enough energy to play more.
It's a good free time filler, but patience, patience, patience!
