Type your country's flag emoji (e.g., 🇹🇷 🇺🇸 🇬🇧) to send support
Each emoji is +1 support for your country in this round. At 10 supports its flag gets its first shield.
FlagsBattle is a live interactive game where country flags compete in a physics-based arena. Unlike pre-recorded videos, everything happens in real-time, and you control the action through live chat!
Flags bounce and collide in a spinning ring, and a flag that falls through the gap is out. The last flag in the ring wins the round, and the first country to win 3 rounds is the champion. Viewers help their favorite countries by typing flag emojis in the chat: every emoji is one support, and supports earn shields.
Every flag emoji you send in the YouTube live chat is +1 support for that country in the current round. Supports build tiers, and tiers give the flag shields.
You send: 🇹🇷
Turkey gets +1 support. Supports from all viewers add up, and every flag in a message counts: 🇹🇷🇹🇷🇹🇷 is 3 supports.
You send: 🇧🇷
Brazil gets +1 support. At 10 supports in the same round it reaches Diamond 💎 and gets its first shield.
The game counts every flag emoji you send. The channel's own chat rules still apply, though: slow mode can hold your messages back, and the streamer's moderators can time out anyone who floods the chat.
FlagsBattle has three game modes. Each round starts after a 10-second countdown. The last flag in the ring wins the round, and the first country to win 3 rounds is the champion.
The classic mode. The ring spins with a gap in it, and a flag that falls through the gap is out unless it has a shield. From 20 seconds the gap widens and the ring spins faster. At 30 seconds the game calls TIMEOUT! and opens the gap wide.
The ring is closed, so no flag falls out. Instead, random lightning strikes eliminate flags, and shields do not protect against lightning. The last flag left wins.
Maximum mayhem! The arena shrinks, random events trigger constantly - vortexes pull flags, wind pushes them around, speed bursts occur, and chaos spins everything. Expect the unexpected!
If a Normal or Chaos round lasts 2 minutes and a supported flag (one with a tier) is still in the ring, the game calls HYBRID MODE! Lightning then strikes every 3 seconds, and 70% of the strikes aim at supported flags.
While most interaction happens through flag emojis, there's one special text command available:
KKTCNorthern Cyprus has no flag emoji, so typing KKTC in the chat gives it +1 support instead. It does not add Northern Cyprus to the arena: it only helps when the streamer has it in the game. This is the only text command.

To keep FlagsBattle fun for everyone, please follow these basic rules:
FlagsBattle reads your live chat with your own free YouTube API key. The game runs and streams without one; the key is needed for chat play, so your viewers' flag emojis become supports. Setting it up takes about five minutes and you only do it once.
Open Google Cloud ConsoleOpen Google Cloud Console, sign in with your Google account and create a project with any name, for example "FlagsBattle". Make sure it is selected at the top of the page.
In the API Library, choose YouTube Data API v3 and click Enable.
Go to Credentials → + Create credentials → API key and copy the key. It starts with AIza. Recommended: open the key, choose Restrict key under API restrictions and tick only YouTube Data API v3.
Open the app and, in the right panel under Tools, click YouTube API (the key icon). Paste the key, click Save & Apply, then Test Connection. Both lines should show ✅. The app remembers the key.
In the app's left panel, under the Chat switch, paste the link of your YouTube live stream into the Paste your YouTube live link box and click Connect. The status should read Connected, reading chat. Every step of the setup: the streamer guide.
Never share your key or show the settings window on stream. If it leaks, delete it under Credentials and create a new one.
All flags follow the same physics rules. Each stream is run by its streamer, who moderates the chat and can time out anyone who abuses bugs, floods the chat or provokes others. The streamer can also turn on Creator mode, which protects the countries they pick.
Representation & Content Note: FlagsBattle does not make political/ideological evaluations regarding countries, cultures or communities. This is a game and simulation experience.
Jump into the action and support your country in the next battle!
