Need tips on Freeroll poker.

As we all know freeroll poker is a totally different game. There is basically no strategy going on with an exception to a few. I would like a few tips on how yall would go at freerolls. I do pretty good by getting past the initial donk fest of all ins. Thx guys. I usally start off playing pretty tight for the first few levels, then open up as I get a bit of a read on the table. Any tips i would appreciate.
