Roughly 45,000 visitors from all over the world are expected to come to Dreamhack Winter in Jönköping over the weekend.

The festival already started on Thursday when the LAN party, where you play computer games non-stop for four days straight, got underway.

To cope with that, energy drinks can work as a helping hand.

Dreamhack's PR team expects that thousands of liters of energy drink will be consumed over the weekend.

- It's a small amount, so far I've drunk ten, says visitor Max Larsson.

But in addition to jogging and drinking energy drinks, you can also participate in various competitions and win prize money.

In total, it is about eight million kroner that the festival competes for.
