Rivals

I don't get why anybody enjoys the "game". All you do is push a button, and it makes a few noises and then either lights up or doesn't. And that's it. There seems to be no continuing aspect where you play from round to round, no rules, nothing. Everyone acts like it's this really intriguing form of gambling, but how is it any different than just flipping a coin? Connect a light to a little random number generator, add a couple of little sounds, and that's this device in a nutshell. I wondered if maybe the device was supposed to be manipulating people's minds to make them think it's interesting when it's obviously not, but that really doesn't seem to be the case.
