Assembly is the biggest computer festival in Finland and the biggest demoscene event in the World, organized time in 1992. These days Assembly is organized two times a year, once in winter and once in summer.

The event provides a lot to see and experience centered around gaming, computer hobby, and digital trends. Assembly hosts the largest LAN area in Finland, multiple program stages, and the EXPO area for our partners to host and display their own activities. The party  program consists of shows revolving around computer culture, seminars, contests, and meeting similar-minded people. Assembly is a place to play games, meet friends, follow the show, take part in activities and tournaments, and discover what the different partner stands have to offer.

Tickers are sold in two kinds:

  • LAN seat tickets for party goers with their own equipment (computer, console)
