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 the team and competed in an IGS event for another team, he or she becomes ineligible for prize money.
- 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.
