You can create a tournament from two places:
You'll need to provide:
The star icon () lets you mark your favorite leaders:
A bye round is when you receive a free win because there are an odd number of players. Bye rounds:

Note: The "Edit Tournament" button only edits tournament details (title, leader, format), not individual rounds.
When you're finished logging all rounds:
Once completed, you can no longer add rounds, but you can still edit tournament details.
This marks your most recent round as a "drop" (when you leave a tournament early). Dropped rounds are excluded from win rate calculations, similar to bye rounds.
Top Cut refers to the elimination bracket that happens after Swiss rounds at larger tournaments. Players who perform well advance to single-elimination matches where each round is best-of-three.
Example: A tournament might have 7 Swiss rounds, then Top 8 elimination with best-of-three matches.
Once you add your first Top Cut entry, the "Add Round" button disappears (Swiss is locked).
Each Top Cut round has three possible games:
Validation: You can't have three wins (WWW) or three losses (LLL). Maximum is 2 wins or 2 losses per round.

Your win rate shows the percentage of matches you've won:
Important: Win rate excludes bye rounds and dropped rounds. Only actual matches count.
Example: 8 wins + 2 losses + 1 bye = 80% win rate (8/10).
Player Identity is a visual summary of your playing style shown on the home page. It displays:
The gradient background dynamically changes based on your most-used leader's colors.

Bye rounds and dropped rounds do NOT count towards or break streaks.
The trophy counts show your tournament placements:
Only completed tournaments with final placement data count towards trophy totals.
Recent Form shows your last 5 match results with color coding:
Bye rounds are excluded from recent form.
The Leader Win Rate module shows:
Leaders are assigned at the tournament level, not per-round.
These show your performance based on who goes first:
