An additional 400 tickets per session are available for the Cazoo World Cup of Darts in Jena.
The annual 32-nation tournament will be held from September 9-12 at the Sparkassen-Arena in Jena, Germany.
Tickets had initially been limited to 500 per session, however PDC Europe have been able to increase this to allow more fans the chance to see the unique pairs event live next month.
"We know exactly how popular the World Cup of Darts is with fans and have done everything we can to give as many people as possible the chance to celebrate a great darts event with us," said PDC Europe Director Werner von Moltke.
"With last year's events we have shown that we can hold safe events in a great atmosphere even under difficult conditions. Hopefully, the increase in capacity at the World Cup is another step towards normality."
