I have a question about suing subdomains inorder to get better ranking.
ec to make subdomain A with they keyword games.domain.com
B with the keyword casino.domain.com then redirect the subdomains directly to your head domain.
This creates a new website that points to your domain, but how mutch does it help the ranking in time?

nobody????

In general, sub-domains are like a separate site, so only useful if the main domain has some authority (or you're going to build links to it). You could use them for low competition EMD terms, e.g. brand1.games.com, brand2.games.com, but if you are looking to build an authority type site, better to use a folder structure like games.com/brand1, games.com/brand2.

Also in your example above, instead of using sub-domains to rank for different terms, it may be better to use/build a private blog network.

In order to build a private blognetwork, how does this work? can I do this on the domain?

You're on about building a network of sites which happen to be the same domain but on subdomains, well this works for a short time (if at all these days)

You might as well build yourself some link wheels at the same time and be proper done with it

Better to use different domains. This gives you an idea about building blog networks:
