CIRCUIT STAGE

The TETR.IO World Championship is split into 2 stages: the Circuit Stage & the Main Event. The Circuit Stage runs from January 31st to July 31st.

Participants earn Qualification Points by competing in tournaments hosted by participating communities. Their Top 4 Platinum/Gold Tournament Results (in terms of points) and their Top 5 Silver Tournament Results (in terms of points) will be tallied up and shown in the Ranking.

Qualification Points can be earned according to the following distribution:

Starting in April, at the end of each month, the Top 16 players with the highest amount of Qualification Points that have not yet qualified will receive an Invite for the World Championship Main Event.

In the event that two or more players have the exact same amount of Qualification Points, the following tiebreaker strategy shall be utilized:

  • Best individual result (in terms of points)
  • Second best individual result (in terms of points)
  • And so forth, until all points are exhausted.

In the case that all four Platinum/Gold results and all five Silver results are equal for two or more players that contend for an Invite, a tiebreaker bracket will be set up between the players. The format for this tiebreaker will vary depending on the amount of players who must play in it.

  • 2 players: A single FT11+2 match
  • 3 players: Round Robin; FT11+2
  • 4+ players: Single elimination bracket; randomly seeded; FT11+2
FORMAT
