Not played by my rules but..
In my family, you have to play the trump "life" card if you have one and another one had been thrown.
If the life is gold, and I throw a old first, the computer would then have to throw a gold if it had it. At first I thought this was the case, so I thought that the computer would have no gold. However it did, and won a lot of points from my folly.
It is still a great game!
