No follow question

[Baydak]

I have some "feeder sites" whose purpose is to attract traffic & google juice to build my main site: For example: My learning games for kids site exists not just as a public service, but to gather google juice (and traffic) and send it to my homeschooling site.

- Does the google juice dissipate across the the links to other sites where the games exist?
- Would a no-follow attribute solve this?
