The Panel App is super easy, install it, and let it run in the background. It pays points per day and you can get gift cards for those points.
I usually get the $25 Amazon gift cards through it (15,000 points). That is the highest payout for the least amount of points.
You can use the points from the Points Panel or the Bonus Panel to enter in giveaways and sweepstakes.
They do offer surveys occasionally that give you additional points. They are short surveys of 2-5 questions sometimes.
You also get extra points from referring friends, too.
