They also added a new way to earn SB's via a Facebook App, which can be found here. For the details check out this entry on the Swagbucks Official Blog.
Here's a brief summary I copied from the SB's blog.
The trivia itself is a 10 question, timed round.Users will have 5 minutes to complete all 10 answers correctly, and to help you arrive at the right answer, we’re including a Swagbucks.com search box right underneath the questions. Note, this is going to help you maximize your searching Swag Bucks as you play trivia! Answer any question incorrectly, and the round is over. Each user has a total of 5 available rounds per day, and once completed, you must wait till the next day before having another chance to earn. Assuming that you complete all 10 questions correctly, you will either earn Swag Bucks on the spot, or be awarded with your Token. You may then chose whether to keep playing trivia, or to press your luck on the Spin&Win
That's all for now, I'm anxious to check it out and start winning more SB's!
