Arcade games are the ancestors of modern video games, where the first arcade game is a coin-operated machine. That was in 1947, and everyone was impressed by the graphics seen at that age so that in the late 1970s and early 1980s there were a lot of technology-based arcade games for computers (they were expensive).
Now we have not only user-friendly operating systems but also smartphones with very good capabilities and Android is a system so complete that it allows having fun with little money since it’s cheaper than any console.
So the huge growth of arcades made many game developers create new android versions of their already existing games for the arcades.
They are video games that have been created with arcade machines in mind.
