Because this format is new to the 1v1 circuit not everyone may be familiar with the format so I've included an example 64 player rundown below. If you have any questions feel free to reach out and ask because it's better to find out now than during the actual tournament.
Round 1: Stage 1 - 2 sets of 32 Bo5 matches (64 unseeded players, subs period) & Stage 2
Round 2: Stage 1 - 2 sets of 16 Bo5 matches (32 unseeded players) & Stage 2
Round 3: Stage 1 - 2 sets of 8 Bo5 matches (16 unseeded players) & Stage 2
Round 4: Stage 1 - 2 sets of 4 Bo5 matches (8 unseeded players) & Stage 2
Semifinals: Stage 1 - 2 sets of 2 Bo5 matches (4 unseeded players) & Stage 2
Finals: Stage 1 - 2 sets of Bo5 matches (2 unseeded players) & Stage 2 (essentially a bo3o5 in finals)
-----------------------------------------
Stage 1 End: Players with 2 match wins go through, and those with 2 losses are eliminated.
Stage 2: Players with a 1-1 record play each other in an Bo5 match to see who progresses (or wins the final).
Each stage is 1 week long and each round is 2 stages equalling 2 weeks long.
Basically you just have to win 2 out of 3 potential games in order to move on to round 2.
Example
If you are given Murman and Lumii as opponents for the first round and win against one of us but lose against the other, you will go to Week 2. If you win against both of us, you will advance to the next round. If you lose both, you will be eliminated.
