Internet accessibility and new online technologies flourished, such as Java and Adobe Flash. Though Adobe Flash was initially intended to be a tool to develop fully interactive websites, Flash lost favor in this area but individual developers found ways to use the tool for animations and games, aided by the ease of the development tools for this purpose. The website Newgrounds was created to help people share and promote their Flash works. Though these Flash games lack the complexity of gameplay of games on consoles or computers, they were available for free and sparked creative ideas that would carry forward; for example, Crush the Castle directly inspired the popular mobile game Angry Birds, while the founder of Newgrounds, Tom Fulp, teamed with animator Dan Paladin to create Alien Hominid as a Flash game, which they later built upon into the more complete Castle Crashers under the studio The Behemoth. Flash and other in-browser platforms created a new trend in casual games, with limited complexity and designed for shortened or impromptu play sessions.

These games, often based on casual game mechanics, typically rely on users to interact with their friends via the social media site as to gain a form of "energy" to continue to play. Happy Farm, released in China in 2008, is considered the first such major social game. Influenced by the Japanese console RPG series Story of Seasons, Happy Farm attracted 23 million daily active users in China. It soon inspired many clones such as Sunshine Farm, Happy Farmer, Happy Fishpond, Happy Pig Farm, and Facebook games such as FarmVille, Farm Town, Country Story, Barn Buddy, Sunshine Ranch, Happy Harvest, Jungle Extreme, and Farm Villain. Happy Farm served as direct inspiration for FarmVille, which had over 80 million active users worldwide by 2010. Rise of mobile gaming Separately, gaming on mobile devices had limited success until
