Journalist Chris Kohler wrote in 2010 that
Namco's
arcade game Pac-Man (1980), which debuted during the
golden age of video arcade games, may be the first casual video game, due to its "cute cast of characters and a design sensibility that appealed to wider audiences than the shoot-em-up
Space Invaders." It is estimated to have been played more than ten billion times during the 20th century, making it the
highest-grossing video game of all time. In 1989,
Nintendo's
Game Boy was released with
Tetris as a free pack-in game. It was quickly learned and immensely popular, and is credited with making Nintendo's fledgling
portable gaming system a success.
Microsoft's
Solitaire (1990), which came free with
Microsoft Windows, is widely considered the first hit "casual game" on a computer, with more than 400 million people having played the game . Subsequent versions of Windows included casual games
Minesweeper,
FreeCell, and
Spider Solitaire. The company published four
Microsoft Entertainment Packs for casual gaming on office computers from 1990 to 1992. Casual games started to flourish online in the 1990s along with the rise of the
World Wide Web, with card games and board games available from paid services like
AOL and
Prodigy, and then from web portals, like
Yahoo! Games and Microsoft's
Gaming Zone. In the mid-2000s, more sites specialized in game hosting and publishing, such as
Gamesville and
RealNetworks. Some publishers and developers branded themselves specifically as casual game companies, like
Big Fish Games,
PopCap Games, and
MumboJumbo. The advent of
Shockwave and
Flash created a boom in web-based games, encouraging designers to create simple games that could be hosted on many different websites and which could be played to completion in one short sitting. One of the most prominent casual games,
Bejeweled, started out as a Flash game that could be downloaded for a fee, or purchased at retail. As late as 2009, there was still a market for US$20 casual games purchased at retail or as a download. In 2008 and 2009, casual
social network games rapidly attained mainstream popularity following the release of
Mafia Wars for Facebook, and
Happy Farm in China.
Happy Farm inspired many clones, including the most popular social network game,
FarmVille (2009), which peaked at 83.76 million monthly active users in March 2010. These games innovated in
viral marketing by rewarding players for sending invites to friends and posting game updates on their
Facebook Wall. Casual games became popular on
mobile phones, devices that turned ubiquitous among a wide variety of people during the 2000s, and these phones often had preloaded
clones of classic puzzle video games like
Tetris,
Qix, or
tabletop-based games. The phones gave all-day availability to the phone owner and helped popularize casual games for many. Newer
smartphones, with large color displays and intuitive tapping-and-dragging user interfaces, gave way to a rising industry during the 2010s with high accessibility through downloadable
app marketplaces.
Video game consoles' primary audience is hardcore gamers, but there are some casual games on every game console, and Nintendo's
Wii console's unique motion-sensing controller appealed to a more casual audience that was perhaps intimidated by other consoles'
gamepad input devices.
Wii Sports (2006), a collection of five simple sports games in which players used the game controller to swing a tennis racket or a baseball bat, was bundled with the Wii console in most territories and sold over 82 million copies as of 2019. == Genres ==
