control 3x 7 segment single digits with 6 buttons

@CrossRoads
it will (2x) 2 digits and (4x) 1 digit displays

only showed an example pic for (3x) 1 digits.. the entire project..

also not shown will be the last button with an rgb led to select level..
green=easy, yellow=medium, red=hard.. this button will control the left side digit displays as well call a new game every time the level is changed.. as well as an on/off switch with and led for power indicator.

so as you can see, there is alot more going on than the (3x) 1 digit displayed in pic 1

my buddy made this game for the DS awhile back.. my intent is to reproduce it with the arduino.. put it in an enclosure with a mini arduino board and battery pack and send it to him - as well make a copy for me lol.
