Hi, just take a look at a list of tables I can join, and I noticed there is a table called 'duck's race'. What exactly is that table? When I go to create a table, I don't see this in the list of possible tables to create.

Hello. It is a new game that was launched as a test for a smaller period of time. This game will according to the administrators be available for everyone on sunday, so just be patient and you will be able to play it.

I see.

what is the hour of release?

Being patient is not a bad thing. That's precisely why developers do not like announcing release dates. However, the admins said on the French part that it will be 13:30 French time.
Edit: While you are bored waiting for the game, feel free to read the rules, which have been published at https://qcsalon.net/en/coursecanards
