I have been using Swagbucks for years. It isn’t a huge money maker, but I earn enough points to get at least a $25 gift card every month. There a tons of retailers to choose from an they even offer discounts once a month. I like to get a Walmart gift card monthly for 2,200 points. I add them to my Walmart account and save them for Christmas. These are actual screenshots from my account and earnings. It shows earning for the last year, as well as lifetime.
There are tons of popular games to chose from and more a constantly being added so you won’t get bored. Some games also offer bonuses if you complete a level in a certain amount of time. There is no requirements to buy anything but there are of course bonuses for spending real money. I do not spend real money on playing games.
Games aren’t the only way to earn points. You can also get points from web searches, surveys, submitting receipts, online shopping, etc. Daily polls and daily bonuses help you reach your points goal faster. If you are interested in signing up, you can follow this link.
