The Intel Grand Slam in Season 3 can be completed by the first team to complete either of the two conditions below:
1. Winning six ESL Pro Tour Masters tournaments inside a span of ten consecutive events.
2. Winning four ESL Pro Tour Masters tournaments inside a span of ten consecutive events, inclusive of a Championship level ESL Pro Tour event (any of the IEM Katowice or ESL One Cologne Masters Championships or a CSGO Major Championship by ESL or DreamHack).
The list of eligible IGS Masters level events & championship level events is available on the Intel Grand Slam website.
- Results from the previous season of the Intel Grand Slam are not counted towards the current season of the Intel Grand Slam.
- Teams are allowed to swap players between tournaments, but a core of the same three players has to win four finals together in order to be eligible for the Intel Grand Slam.
- If a player has left his or her team and competed in an IGS event for another team, he or she becomes ineligible for any IGS prize money his or her old team would win.
- If a team that is about to complete the IGS is stopped in the final of their potential 4th win, their opponents receive the $100,000 “giant killer bonus”. The one exception to the rule is if a team denying the completion of the Intel Grand Slam completes it in the same final.
- There is no limit to how many giant killer bonuses are paid out in a single Intel Grand Slam Season.
