LED Noughts and Crosses

[Ahud]

I am actually new to the multisim which was introduced by our school. I am having trouble in making the circuit below in the multisim. It seems that I coudn't find the tri-color LED. Could anyone help me in constructing the circuit? I am also having trouble on how will place my switches and LEDs because it has supposed to be 18 switches and 9 LEDs. Any help would be gladly appreciated.

Hi Ahud,

Multsim doesn't have a tri-color LED, you have to use two separate LEDs a red and green placed close together and when both LEDs turn on that will represent the  third color.

There are many switches in Multisim, go to "Basic" group and select the "Switch" family.  Use two DIPSW9 switches, one for each player.
