Wales Coach Iestyn Harris says he hopes hosting the competition will help raise the profile of the sport in the country.
The Millennium Stadium's hosting the Cardiff Mind Sports Festival this weekend, with some of the UK's biggest board game experts playing at the venue.
The festival's also open for the public to take part and sees a variety of tournaments including Chess, Scrabble and our favourite card games.
"There's a huge audience that want to come and play," said Peter Ramsay, Marketing Director of Mind Sports International.
"In terms of the prize fund it's everything from small bragging rights to trophies to 2,000 to 10,000 pounds in euros.
"This is the first of its kind to come to the UK, it's the first ever to come here in Wales and its the largest one of its kind so far to dat."
The new manager of the Millennium Stadium, Mark Williams, says it is a "dream job" and a "privilege" to be in charge of Wales' leading sporting venue.
Williams will take up the post later this month, after leaving the army, where he is a Lieutenant Colonel.
A decorated senior army officer has been appointed as the new manager of Cardiff's Millennium Stadium.
Mark Williams, from Glynneath, is a Lieutenant Colonel in the Royal Welsh, and served in Northern Ireland, Bosnia, Kosovo and Iraq.
He was decorated for his actions in combat in Iraq, where he led Welsh soldiers on many missions into Basra in 2007.
Now 42, he joins the Welsh Rugby Union later this month on his retirement from the army.
In his new role, he will have responsibility for the operation of the Millennium Stadium, owned and operated by the WRU.
He replaces Gerry Toms, who stepped down in March from what he described as the best job in Wales.
Mark Williams said: "I am deeply honoured to be joining the WRU in such an important role and I relish the challenges and opportunities this represents for me. As a proud Welshman and rugby supporter I understand the important place the stadium holds in the whole psyche and culture of Wales."
