Thank u gandora , for ur kind response,

Actually i want use 3*3 LED matrix for display (Bicolour LEDs if possible)

and some keys like those in the calculators .

With out interfacing with PC will be better

our game should have two options 1) one player mode (i.e, playing with pic)
2) two player mode
and peizo buzzer to announce the winner.

main aim is to keep things as simple as possible!!!
