The early DHTML games were very simple. Some examples of the games back then were Tic-Tac-Toe and Snake. As games made with this technology use the open standard of HTML5, these relatively ancient games are still playable today in a modern web browser. These technologies have moved to the forefront of browser games because they don't require plugins and are safer to play than older technologies. HTML5 games also support mobile devices and the capability has improved to support complex 2D and 3D games right in a browser.
