ELO is a rating system, originally from chess, that ranks players by skill. After each match, points move from the loser to the winner — and beating a stronger opponent earns more than beating a weaker one, so ratings settle around each player’s true level.
Anything head-to-head — ping pong, chess, pool, darts, foosball, basketball, soccer, video games — plus cumulative challenges like running or push-ups through volume mode. Each sport has a recommended setup guide.
No. You can add players by name, and people can join a league or tournament from a shared link or QR code without signing up. A free account just lets them follow standings from their own home screen.
Yes — single or double elimination brackets, seeded automatically by ELO, with byes handled for you when your player count isn’t a power of two.
