Browser games are a category of online games in which the Web browser acts either as an operating shell for the game, allowing you to play the game without installing additional software on your computer, or serves as a container for additional virtual machine that directly executes the game code (Java, Flash, Shockwave, etc.). Games of this type are most often casual games, which is due to restrictions on size. In addition, browser games are popular with developers of commercial gambling games, particularly online casinos, due to the lack of installation process of the game on your computer.
Browser games can be both free and paid. As a rule, they offer the opportunity to play for free, but motivate the player to pay for some in-game services. There are games that allow you to redeem game currency or points for real money.
Client Games.
Another large group are games that use client software written specifically for this game or a group of similar games. Conventionally, this group also includes built-in games in some programs, such as ICQ. It is possible to allocate separately IRC-games with the text interface which are realized by means of IRC-bot. It is also possible to add the so-called MMORPG.
These games include: Ultima Online, Ragnarök Online, Lineage 2, World of Warcraft, EVE online, Perfect World, Aion.
Some browser games allow you to play them not in the browser, but with a specialized client. An example of this game: Heroes of War and Money.
Casual Games
Casual games are very simple structured games that are very short – usually the game starts and ends within a single session of being on the Internet. The casual games include a variety of puzzles, shooters, etc. Unlike other types of online games, casual games are mostly single-player.
