1v1 or co-op
with your mate.

Duelo is a head-to-head games app. It bundles eighteen games — word games, board games, a trivia quiz, a drawing game and more — and lets you play any of them against one specific friend. All eighteen work live; nine of them also work asynchronously, so neither of you has to be online at the same time. Every result feeds a permanent record against that person.

Yes. Anytime mode lets you send a challenge your opponent plays whenever they like; the app compares your results and updates your head-to-head record. This is the mode most people end up living in, because live play needs two people free at the same moment.

Free to download, with no ads and no subscription. Six games are free: Word Chaser, Word Brawl, Fleet Hunt, Four in a Row, PIVOT! and Know Me. One payment unlocks the rest, and joining a game a friend invites you to is always free. The purchase grants no competitive advantage of any kind — it cannot buy you a win.

A person you chose, every time. You invite a friend, or send a challenge link to anyone. There is no matchmaking, no queue and no stranger pool. There are no bots either — nothing on a leaderboard that isn't someone. If they're not online, you leave a challenge instead of playing a machine.

Crossword Chaos (Real-time clue duels), Word Chaser (Hidden-word hunt), Cluster Clash (Group the words), Cipher Storm (Five-letter word race), Path Pursuit (Trace-and-claim word grid), Anagram Race (Same letters, most words), Four in a Row (Drop & line up four), Fleet Hunt (Find and sink the hidden ships), Dots & Boxes (Draw a line, close the box), Mancala (Sow, steal, fill your store), Trivia Duel (Right and fast wins), Doodle Duel (Draw it, guess it), Know Me (How well do you know them?), Word Brawl (Words are punches), Snake Battle (Two snakes, one garden), Bomb Pass (Hot potato, but explosive), Trapdoor Panic (Cross the hidden minefield), PIVOT! (Carry it together).

Live means both players are online at once — either racing the same board simultaneously, or alternating turns on a shared one. Async means one player sends a challenge and the other answers it later. Async is what keeps a rivalry alive across time zones and busy weeks.

Yes. In PIVOT! you each carry one end of a sofa, a fridge or a grand piano across busy streets, stairwells and a level crossing. There's no loser and no rating: you get it there together or you don't. Play online on two phones, or both on one.

On an iPhone, yes: sixteen of the games play right inside Messages, and Snake Battle and PIVOT! send an invite that opens the app. No account is needed in Messages. Android friends play every game in the app.

Competitive duels are rated with Glicko-2, the system used in competitive chess. Unlike plain Elo it also tracks how confident it is in your rating, so a new player's number settles quickly. Co-op games are unrated, because a shared solve has no losing side.

You need one to keep a head-to-head record against a specific friend, since the record has to belong to someone. Joining a live room a friend has shared works from a link.
