Best strategy for maximizing value on a 20-bet bonus?

I'm trying to take advantage of a new welcome bonus that gives us 20 free bets, but I'm completely overwhelmed by the terms and conditions. Specifically, I'm unsure if the wagering requirements apply equally across different game types, like slots versus live casino tables. Has anyone here successfully used a large bonus like this before? I'm looking for advice on whether I should spread the bets out over several days or try to clear them quickly to minimize risk. Any tips on managing the playthrough requirement would be greatly appreciated.
