Need help building a "concentration" game

Dear all,

I have my ganglion board and electrodes for a few weeks now, and use it in combination with Brain Bay.
The idea was to have fun with neurofeedback and perhaps train my meditation skills AND make a "concentration" game for my kids (and oh well, for me too).

Setting it up is done, and I would love to get things done through the Fp1 & 2 spots, as this does not require paste in our hair :)
When I try it myself, I never see strong results in the beta band, but when I close my eyes, I get readings at the 11-12Hz range. Also 3-5Hz goes up.

I don;t see very strong reactions, not when I am 'musing', not when I am intently reading new stuff or doing calculations in my head (which should stimulate beta).

The amplitude is usually in the range of 20-30 uV.

I just can't seem to find what readings I should get when concentrating, or when relaxing or attempting meditation. I am not new to meditation, and do know how that state should feel (or perhaps I am doing it wrong for many years, which is not ruled out here).
Most of you have experience with this, I guess. Could you point me to articles, tutorials, or give me hints?

My goal is to make two minigames:
1) for stimulating alpha waves. Done by audio feedback, as alpha is easier to maintain with eyes closed. Can be that a white noise gets louder of perhaps softer by getting to stronger alpha waves in 8-12Hz. The brainbay example did kinda work, except I would get excited (or jumpy) when the music actually jumped up, which would immediately get me out of alpha. Hence I thought that softening the music by getting in Alpha would work better? Suggestions anyone?

2) I made a mini game in gamemaker with a single keystroke, where a tiny death star would float up upon keystroke and lower when no keystroke was detected. Want to use the keystroke event in Brain Bay for that, to get to a more concentrated state. Jedi stuff... :)
This would require higher SMR and lower Theta, right? 

I just can't seem to get distinct enough signals from the EEG to use that in the calculations. 

Does anyone have pointers for me?

    What I am actually asking first is this:

    How do I know the data I get is accurate enough to work with. I can always amplify the data I get to do what I want in my "games". but I need to be sure first that I am measuring at the right sites and getting results that reflect what I am doing (concentrating or meditating). I don't feel that is accurate now. How can I assess the data and know they reflect the right thing to train?

    Lidia, hi.

    Not sure if you have seen these,

    PS your idea about the alpha feedback, makes sense, just try it out.
