Dance Central

Because I beat Pokerface with 5 stars and no flashcards already and it didn't unlock for me, this is what i did.

Key: In the Dance Central manual, it says that all signed in profiles will get achievements unlocked.

1. Go back to the main screen, sign in a secondary profile in addition to the one you want. (Your main profile should stay signed in.)
2. Hit start, and choose your secondary profile. (All songs should be reset for that profile.)
3. Play Pokerface on easy (or anything else), and stop moving once you get 5 stars. (This is to unlock no flash cards and to keep score low.)
4. Play again with no flash cards and shake your booty.
5. Should pop for both profiles.

Good luck!

Obviously, Poker Face on easy is the way to go for this one. It has fairly simple moves, and an easy to remember routine. It's definitely worth noting that I did get five stars twice with no achievement popping. Once I got 5 Gold stars, achievement bliss, so the description is a bit mis-leading. If you're having trouble, just watch the on-screen avatar for cues, or just play it a few times with cues turned on and you should have no problem wrapping this one up.

*As pointed out by BCPotter, it MAY have to do with your high score, as in if you have already beaten the song with flashcards turned on and scored high, you may have to be your beat your previous score in order for the achievement to register. I will try to confirm this on another account. I just assumed it had to do with Gold Stars because it was all I had to go on.*

•As pointed out by Curtieson in the comments below, to achieve 5 stars on Poker Face, a score of 400,00 is needed.

The other two guide do a good job in explaining what you need to be aware of in order to unlock this achievement. A suggestion that I have that worked for me was I had my laptop next to me while I was dancing poker face and I went to youtube and looked up a performance of poker face on easy. Then I made sure I started the song at the same time as the video on youtube and then I simply followed the flashcards on the video while doing it in no flashcard mode. This might be helpful for people like me who suck at dancing and memorizing dance moves lol. This strategy could be used for the other no flashcard achievement as well

Note that the reason I don't have the achievement unlocked at the time of this writing is because I failed to read the guides beforehand and had a problem with the highscores. I got the 5 stars but achievement did'nt pop because of this.
