Frequently asked questions
What is Karaogle?
Karaogle is a free, browser-based karaoke game where you're matched 1v1 with a random opponent from anywhere in the world. You both sing the same song with the lyrics on screen, and an automatic judge scores pitch, rhythm and lyrics to decide the winner — with nothing to download and no account needed to start.
Is Karaogle free to play?
Yes, completely. You can jump straight into a karaoke battle without paying or signing up. A free optional account simply lets you save your rating and climb the global leaderboard.
How does an online karaoke battle work?
You pick a genre and get matched with a random singer for a 1v1 duel. Both players receive the same song and sing their turn to the on-screen lyrics. When you both finish, Karaogle scores each performance from 0 to 100 on pitch, rhythm and lyrics, and the higher score wins.
Can I sing karaoke with a random stranger?
Yes — random matchmaking is the core of Karaogle. Press play and you're paired 1v1 with a random opponent from around the world for a real head-to-head karaoke battle, no friends or invites required.
Do I need to download anything or create an account?
No to both. Karaogle runs entirely in your web browser, so there's nothing to install, and you can play instantly as a guest. Creating a free account is optional and unlocks your Elo rating, the leaderboard and friends.
How does the scoring work?
Karaogle scores every performance automatically on three things: pitch (how accurately you hit the notes), rhythm (your timing) and lyrics (the words you actually sang). Each singer gets a score out of 100, and the highest total wins the battle — no human judges, no bias.
Can I play with a friend instead of a stranger?
Yes. Alongside random matchmaking, you can create a private room and share the code with a friend to battle them directly, one on one.
What do I need to play Karaogle?
Just a modern web browser on your computer or phone, with a working microphone and camera. There's no app to install, no plugins and no special equipment.
What languages is Karaogle available in?
Karaogle is available in over 50 languages, so you can sing and play in your own language wherever you are in the world.
What is the global leaderboard?
Every ranked battle you win raises your Elo rating, the same system used in chess. The global leaderboard ranks the top Karaogle singers worldwide, so you can compete to rise from newcomer to champion.
