Thanks to the hard work of @GreenAsJade we now have Rengo! To create a Rengo game simply check the ‘Rengo’ box when creating a new game on the play page.
You will then be brought to a match making screen where you can form up your teams. You can play any number of players against any number of players, players will take turns placing stones for their team in a round robin fashion.
You can see a list of Rengo games available to join in the Rengo game section of the play page.
If you like the feature, don’t forget to reach out to @GreenAsJade and let him know you like it!
Also, a special shout out to @Gozart for putting forth the challenge at the right time such that it piqued @GreenAsJade’s interest enough to make it happen
GaJ Edit:
It seems a good place to note that you can find Rengo games on the Games page using the filter:
TL;DR: Rengo is a form of Team Go, where each color is controlled by a team of one or more (often two) players. The members of each team take turns (in a fixed rotation) for playing stones for their color. There should be no communication about strategy between the players, except to discuss whether or not to resign.
Ohhh something very crazy happened to me…
I tried to accept a normal custom game… I heard the “game started sound” the game appears on my profile, I could watch people playing but it’s not a rengo game!

Ok when the game finished it disappeared from my profile
.
Also thanks for continuous beta-testing
