Yes. Any betting site which offers odds on Team Fortress 2 regularly should have some kind of promotions relevant to those tournaments and markets. Now, unless we’re talking about a site which specialises in eSports, it’s very likely those bonus offers will be broadly available across all sports. In other words, you might get a $10 free bet on sports. Team Fortress 2 should be included in sports and therefore, the promo should be available to use.
