Duels

A duel is a contest between 2–5 users predicting the outcome of one game. Everyone puts in the same stake in $MASK tokens, and the bank is shared by those whose prediction was right.

Creating a duel

Open a game with the “Waiting” status and click “Create duel”.
Choose a market (for example, “Red or Black win”), your outcome and your stake, a whole number of $MASK tokens.
Open duel: set the number of seats (2 to 5, including you) and share the link. Any logged-in user can join while seats are available.
Closed duel: invite 1 to 4 users by nickname or ID. Anyone else who opens the link sees “This is a closed duel”.
The terms of a duel can’t be changed after it is created.

Gathering participants

Your stake is reserved in your wallet when you create or accept a duel.
Participants have 2 minutes to join. If all seats fill up sooner, the duel starts right away.
If not everyone joins within 2 minutes, the duel starts with those who accepted. At least two are needed.
If no one joins, the duel expires and your stake is returned in full.
If all participants picked the same outcome, the duel is dissolved and stakes are returned.

Bank and fee

Bank = stake × number of participants.
The platform fee is 5% of the bank.
The rest is split equally among participants with the right prediction.
Before you accept a duel, you can see how much you could get.

Cancelling

The creator can cancel a duel while no one has joined it.
An invitee can decline before accepting. A closed duel is then cancelled for everyone.
A participant who has accepted can’t leave the duel.
Whenever a duel is cancelled, stakes are returned in full, with no fee.

When you can’t create a duel

Duels are accepted until the game starts. Once the game has started, the market closes and no new duels can be created on it.
