I was given a box full of things and this set was in there, so I decided to put it together. Is there anyone out here that knows what it is supposed to do?

I plugged the battery in and all the LED's light except for the one in position 7 and the switch doesn't seem to do anything. Any help would be appreciated

At a guess I would say an electronic dice.

What are the numbers on the chips? They look like 7400 quad NAND gates and the circuit sure resembles this electronic single die version.

<EDIT> Nope, bad call on my part as this is what I was looking at but more in depth. </EDIT>

The numbers on the chips are HD74Lsoop (3) and 69H4EXK


Edit - I have placed the 69 closest to the power and it works just like the video reloadron posted! Thank you all.
