King of the Mat

The problem
Your gym already has a ranking.
It just lives in everyone's head. Time to put it on the board.
The board
Every honest scrap at open mat, finally on the board.
Confirmed rolls move a rating that knows who you fought. #1 wears the crown — until someone takes it.

Both of you logged it? That happens constantly, and it's fine. If you agree, the two reports merge into one roll and it counts once. If you don't, nothing moves: the second report shows the first one side by side — same roll, or a different one? — and either of you can send it to your coach to rule on.
The math
A two-stripe white belt taps a brown belt.
+345
A brown belt beats a blue belt: +91. Belt, weight and gender are priced in. Upsets pay. Padding doesn't.

Rules of the mat
Five rules keep the board honest.
01
Agree before you roll
Both of you know it counts before you slap hands.
02
A submission ends it
Tap, and the ranked roll is decided. One roll, one result.
03
Log your win, or your loss
A self-logged loss counts instantly. Nobody lies their way down.
04
A win counts when confirmed
Until a result is in, the board does not move.
05
The coach has the last word
Dispute it and the instructor rules. Their call is final.
The game
A throne room, not a spreadsheet.

FAQ
Straight answers.
How does the ranking stay honest?
One fighter logs the roll, the opponent confirms it — nothing moves until they do. Contested results go to a coach, and the ruling is on the record.
Is it fair for lighter or lower-belt fighters?
Beating someone bigger or higher-ranked pays more; losing to them costs less. And every belt and weight division crowns its own king or queen, so there's always a throne in reach.
What if someone ducks a challenge?
Declining costs ranking points — more if the challenger is ranked below you — and it's announced on the feed. If the date genuinely doesn't work, propose another.
What if we both record the same roll?
Expected — and handled. If you both report the same result, the two reports merge into one roll and it counts once, confirmed on the spot. If you report different results, nothing moves yet: the second report shows the first, and you choose — log it as a separate roll, or open a dispute for your coach to rule on. It can never count twice.
Is it really free for fighters?
Always. Academies are free up to 6 members; bigger rooms upgrade to Academy or Club.
Do quests and XP affect the ranking?
Never. Quests and XP celebrate showing up. The crown is decided purely by confirmed results.
