Happy hour is usually on a Monday, Wednesday or Friday at 6-7pm GMT or 7-8pm GMT (I'll update regularly as to if it's on or not/specific days and times)

What it is; It's a period of time in which you have 3x more chance of getting an In Form player or a rare player. EA usually include the Player Premium Pack, which consists of 12 players 3 of which are rare, and costs 25,000 coins or 280 microsoft points. However, you can only buy 5 of these packs during one happy hour.

Autobuyers are programs that you can set up to buy players on UT while your not on your xbox or the web app. For example you can set it to buy a player for a set price and it will buy all the players that are that price or cheaper, obviously until you exit the program. This is a great way to make coins by possibly getting players on the cheap and selling them for profit.
You need to be very careful where you acquire an autobuyer as most of the people on here who are 'selling' them contain viruses/keyloggers, or they're just trying to scam you out of some coins/money, so be careful who you buy off and make sure they are legit/trusted before you do.

There are so many noobs claiming they can do the 'duplication glitch' or they can 'double your coins'.. These are all fake, as most of you know!
If someone says they can dupe your players, do not believe them!

Obviously the 59th minute method.
This is where you skip all the way to the 59th minute in the trade pile (I suggest defining your search otherwise you'll spend all day trying to get to the right page) and look for bargains, some people who aren't that familiar may put up a player for 1k when he could sell for 5k. It also helps if you have a bit of knowledge of players prices as you could think someone is cheap then find out that you can't make a profit on him.


The second account method.
This is a very lengthy process and doesn't pay out brilliantly (possibly 15k an hour if you're quick.)
You need to make a silver account and UT, then delete all your consumables, manager and all your players, this should give you around 4-500 coins. Then all you need to do is transfer the coins to your account by putting a bronze player up for sale on your xbox and buying him on your second account. After you've done that, delete the team on your second account and repeat.


Buy and Boost.
I've found this is a difficult method to use on Fifa 12 for some reason.
What you do is buy any player that has less than 5 contracts, boost the contracts up to around 25 and sell him for a profit.


Buy, Change, Sell.
I've used this method quite a lot and it's really helped me to gain some coinage!
For this method you need to buy a player in a certain position, example; Thierry Henry in CF for around 2k then change his position to ST and sell him for around 7k (might be less not checked on him for a while.)
This also works with RM>RW and vice versa.

The TOTW is released at 3PM every wednesday on the EA forums and are available in packs at 6pm GMT. This consists of the starting XI and 7 subs. The players in the TOTW will have been chosen due to a good performance over the weekend for their club. EA do not include weekday matches or cup matches, although cup finals are sometimes included and in that case they create a man of the match card.
