SecureRandom best practice?

Maybe someone can help me with this.

So far I found that SecureRandom is better than Math.rand, but is hard to find something like a best practice for SecureRandom, for example:

1. How long the seed must be?

2. I am going to use the SecureRandom for multiple games, should I use a global SecureRandom or I should use one per game.

3. For how long the SecureRandom is good, how many numbers can I generate before change the seed?

Articles or books recommendations will be great too.

Thanks.
