YouTube chat plays through Upstream.so.
Chat play stays free, and so does every game in OBS.

Each answer is timed by when it was sent, minus YouTube's delay.
They scan the code on screen and play from their phone.
Why does YouTube chat play need Upstream.so?
Because YouTube limits how much live chat each app can read per day, and a game reading every few seconds burns through that fast. Upstream.so already reads YouTube chat for its multistream chat, so StreamArena uses it, and chat play stays free.
Does YouTube's stream delay ruin the game?
No. YouTube viewers often watch a few seconds behind you, so each answer is timed by when it was sent, minus YouTube's delay, and the round waits for the slowest platform. A late answer shows up a moment later but keeps its place.
