In the last twenty years there has been an explosion in the number of games available on computer and gaming systems. From the earliest computers, games have been programmed to specific instructions by users. Nowadays, computer games can include complex interactive worlds that include hundreds of moving elements such as cars, people, animals, and weather. The focus of the game may be on strategy, problem solving, or entertainment.

Computer and Video games are evolving into an interactive experience with the addition of sound, special effects, detailed images, and numerous options for user modification. A video game is any computer or video game that involves interaction using a user interface (joysticks, keyboards, or infrared light) or physical input device such as a camera, joystick, gun, or motion detecting device. Computer games are played on a computer system that includes a digital computer, memory, processing unit, a graphics card, video display unit, optical disc, and a personal computer or laptop. There are many different kinds of computer games including racing games, word games, puzzle games, sports games, and others. All these different kinds of computer games can be played with other people who have also purchased the same type of computer system and used the same application software or game console to play the game.

There are many categories of computer and video games, each divided into specialized segments. Action, adventure, board game, card game, simulation, sports, and trivia are a few of the broad categories of video games. Each category of video games has its own strengths and weaknesses depending on the type of game, its theme, target audience, and various features. There is a big difference between an action game and an adventure game or a board game. An adventure game requires considerable skill in visual perception and hand-eye coordination as well as in problem solving, whereas a sports game, for example, may require only general physical ability and no particular expertise in the game.

Board games are divided into three main genres. These are strategy, non-strategy, and simulation. Strategy board games require the players to build up strategies and then use these strategies during the course of the game to reach a particular goal. The non-strategy board games are similar to the slots and card games; the players must manipulate random factors within the game environment.

Video games are played using specially designed devices that resemble either a handheld video camera or a computer monitor. Many people have their personal computers at home or in their offices, while others prefer to play video games while waiting for their friends in online chat rooms or in real life. The main article of this type of game is playing cards or die forms. Cards are randomly drawn on a playing card machine or on a computer monitor screen. Die-cast trucks, statues, action figures, television sets, comic books, and movie series are some of the materials that are used to create the playing cards.

Lastly, video games are divided into two main categories. There are games that are controlled by one player and those that involve multiple players in a conflict. Some of the examples of single player games include word games, trivia games, musical chairs, crossword puzzles, and playing cards that have a black suit and a white suit; while the other examples of multi-player games are racing, chess, and gambling.
