What is Duelo?

Short answer
Duelo is a free two-player games app for iPhone and Android, made by Keeda Studios in London. It has 18 games, and you play each one against a friend you pick: live when you are both there, a turn at a time when you are not. It was called WordKO until 2026.

What it is

Duelo is one app with 18 two-player games in it: word races, four in a row, a hidden-ship hunt, dots and boxes, mancala, a trivia duel, a drawing game, a quiz about each other, party games and a co-op game where you carry a sofa together. Every game is between two people. 9 of them also work when you are not online at the same time.

The point is the rivalry, not any one game. Each pair of friends gets a head-to-head record per game, and it never resets. See all the games →

Every game, by what you actually do

The name

Duelo is the Spanish and Portuguese word for a duel. In Spanish it also means mourning, which is why a plain search for the word brings up dictionaries and unrelated pages. The app is the duel: two people, one board. To find it, search for Duelo app or Duelo 1v1 games, or go straight to play-duelo.com.

History

Until 2026 the app was WordKO, a live word-duel game. In 2026 it grew into board games, party games, quizzes and co-op, and took the name Duelo. Accounts, friends and records carried over. Some old store links still use earlier names; they all open the same app.
