How StreamArena works.
StreamArena runs each game as a web page inside your stream: you add one link (or pick a scene in Upstream.so), viewers play from chat or from their phone, and every answer lands on one scoreboard. There is nothing to install for you or for them.
Pick a game
Guessing games, votes and team battles. Every game works with chat, with guests, or both, and the first round teaches it.
Add one link
Paste the game link as a browser source in OBS, Streamlabs or Meld. In Upstream.so every game is already a scene.
Play
In Upstream.so, chat types answers. Anywhere else, viewers scan the code on screen and play on their phone. Guests always can.
Where answers come from.
Chat comes in through Upstream.so, phones join by code, and both land on one scoreboard.
YouTube, Twitch, Kick and Rumble chat in one feed
Timed by when each answer was sent
Guests, viewers in OBS, and viewers on TikTok or Instagram
StreamArena in five facts.
Nothing to install, short rounds and one scoreboard.
In Upstream.so every game is already a scene. Anywhere else, paste the link as a browser source.
Each game is a web page.
Timed by when each answer was sent.
Sometimes right and often hilariously wrong, so every round has someone to beat.
How do you run a round?
From a host remote on your phone or a second screen, with four buttons: start, reveal, skip and next. The game handles the timer, hints, matching, the reveal and scores. Rounds run 20 to 60 seconds, and the first one teaches the game.
How is the winner decided?
By the moment each answer was sent, not when it reached us. Each platform gets a delay allowance, since YouTube viewers usually watch a few seconds behind Twitch, and the round waits for the slowest one. A slow chat changes when an answer appears, never who was first.
Sent 12.4 sSent 12.4 sSame scoreWhat keeps it safe on stream?
Names and free text pass a safety filter before they show on screen. Each player gets one answer every 2 seconds, and a stream processes at most 50 messages a second, so spam can't flood the game. There are no gambling mechanics, and phone answers stay hidden until the reveal.
Which setup fits you?
The games are the same everywhere. What changes is how viewers answer.

Browse gamesQuestions
Do I need to install anything?
No. Each game is a web page. Add its link as a browser source, or pick it as a scene in Upstream.so.
Do viewers need an account?
No. Chat players use their platform name. Phone players pick a name when they join.
How do I control the game while I stream?
With the host remote on your phone or a second screen: start, reveal, skip, next.
Can chat and phones play the same round?
Yes. Chat answers and phone answers land on one scoreboard.
What happens when chat is quiet?
A house player joins when fewer than three people are playing. It stops as soon as your chat wakes up.
What does it look like on stream?
A game fills a 1920 by 1080 frame and scales down cleanly, with text big enough for a phone-sized player. A 9:16 layout for vertical streams and safe areas for a facecam are planned.
Is it free?
Yes. Chat play is free in Upstream.so, on its free plan too, and every game is free to embed in OBS.
