Classic Frogger-Play free with Gamevance: 253gc
Little warning about this one, installs adware. Makes textlinks on all web pages you view and annoying ads, download at your own discretion. Make an account and verify it, play the game, and keep it installed til credited. I had to manually claim credit using the confirmation email. Can be hard to get rid of afterwords, so do on an older computer or one you just don't care what happens to.

Where Hotties Meet: 501gc
Okay at first I was skeptical about doing this, mainly from the title, amount offered, and description, but I got it to work so here we go, the main steps you need to make sure you do for credit:
1)Sign up with valid info.
2)Select no for all offers, warning some are quite offensive with nudity and stuff like that, should not be seen by those under aged.
3)Fill out your profile and make it look legit.
4)When you get the confirmation email, make sure to keep it and activate your account.
5)Later on you should also get an email about your profile being approved, keep that as well.
6)If you don't get credit after 1-2 days, send ticket to request manual credit with both confirmation email and the email about your profile.
