GoodGames has found the secret to making donating to charity easy: gamification. GoodGames hosts a ton of games (provided by Arkadium), letting users donate to a charity of their choice simply by playing. The site funnels ad revenue and money from its sponsors into over 109,000 charities and organizations. Gamers register a charity/organization to themselves and makes a donation of 1 cent for every three times they play.
One cent may not seem like much, but think about how much time you spend playing games online, and if you're like me, then the answer is probably somewhere north of a lot. There are a ton of titles to choose from on GoodGames and users are even allowed to request titles not currently present on the site.
