PAX East takes place in Boston on March 10th to 12th whereas the well renowned SXSW is around a week later on March 16th to 18th.
Each is set to feature a considerable $10,000 prize pool with a $4000 prize for first place. The competition will also reward those that perform with Hearthstone Championship Tour points, with first grabbing 15, second seeing 12 and eight going to third and fourth. These numbers continue to fall with those placed in ninth to 16th positions still receiving two points.
The events are being put on by One Nation of Gamers and Republic of Gamers, with Geico the presenting sponsor.
Up to 156 players will compete in the competitions in a double elimination format.
Esports Insider says: These are two cool and diverse events for Hearthstone to be involved with, and for the scene $10,000 as a prize pool at each is not to be sniffed at.
