LAN tournament

A LAN party is a gathering of people with computers or compatible game consoles, between which they establish a local area network (LAN) connection between the devices using a router or switch, primarily for the purpose of playing multiplayer video games together. The size of these networks may vary from small (two people), to very large gatherings of a hundred or more. Small parties can form spontaneously and take advantage of common household networking equipment, but larger ones typically require more planning, equipment, and preparation.

As of 2013, the world record for the size of a LAN party is 17,403 connected systems, set at DreamHack, in Jönköping, Sweden.

LAN party events differ significantly from LAN gaming centers and Internet cafes in that they generally require participants to bring your own computer (BYOC) and are not permanent installations, often taking place in general meeting places or residences.

Usually, smaller LAN parties consist of people bringing their computers over to each other's houses to host and play multiplayer games.

These are sometimes established between small groups of friends, and hosted at a central location or one that is known to all participants. Such events are often organized quickly with little planning, and some overnight events, with some stretching into days (or even weeks). Because of the small number of players, games are usually played on small levels and/or against bots.

A small LAN party requires either a hub/switch, with enough ports to accommodate all the players, or if all the computers have Wi-Fi capability, an ad hoc network may be set up. This allows two or more computers to connect over a wireless connection, thereby eliminating the need for a wired network, a fair amount of power, and suitable surfaces for all the computers. Providing refreshments is often also a duty of the host, though guests are usually asked to contribute. In larger parties where participants may not all know each other personally, an entry fee may even be charged. Another tradition of some small groups is to purchase large amounts of fast food for consumption over many days. Many LAN participants will also bring food or drink to consume over the course of the party—though they can be held at any hour, many LAN parties begin late in the evening and run through the next morning, making energy drinks a popular choice.
