1v1 games with friends: what 3,198 real games tell us
Ask anyone what makes a good 1v1 game and you will hear about balance, skill and depth. Then watch two friends actually play one. They finish a round, one of them says "again", and that word does more work than any of those qualities.
We wanted to know what that looks like in numbers, so we counted. Duelo records every finished game between two people, so we can see when a pair stops after one game, when they keep going, and, more to the point, when they come back.
What we counted
We took every finished game in Duelo between 11 October 2025 and 24 October 2026 where both players were real people. We removed our own test accounts and every game against a bot. That left 3,198 games between 398 people in 263 pairs, across twenty games, a few since retired: word search races, four in a row, a sea battle, hot potato, a hidden minefield, dots and boxes, a word fight and more.
To see how people play, we grouped games into sittings. A sitting is a run of games by the same two people with less than twenty minutes between one start and the next. That gave us 580 sittings.
Nobody stops at one
Three sittings in four, 75%, went past the first game. The median sitting was three games, 41% reached five, and one in six reached ten. The longest ran to 32 games. A multi-game sitting lasted a median of about thirteen minutes from the first start to the last.
One busy pair could skew that, so we also looked pair by pair. Among the 49 pairs with at least three sittings, the typical pair played on past the first game in 80% of their sittings.
The last three months, after more short games arrived in the app, are even clearer. Since late July, 88% of sittings went past one game and the median sitting was six. Game by game, the share of sittings that went on to a second game looks like this:
| First game of the sitting | Sittings | Went on to a second game |
|---|---|---|
| Word search race | 61 | 92% |
| Four in a row | 43 | 81% |
| Hot potato | 20 | 75% |
| Sea battle | 19 | 84% |
| Word fight | 17 | 82% |
| Word grouping race | 12 | 92% |
| Dots and boxes | 12 | 92% |
An honest caveat: with twenty sittings, one more or one fewer moves a row by five points. Do not rank games against each other from this table. Read it for the pattern: every game with a fast, clean finish sent at least three sittings in four to a second game.
Switching is normal too. In the last three months, 60% of the sittings that went past one game moved to a different game at least once. People do not pick "their" game. They pick the next one.
The second game is easy. The second night is hard.
Here is the number that matters more. We took the 217 pairs whose first game was at least two weeks before our count. Only 22% of them ever played again on a different day. Most pairs had one good evening and stopped.
That 22% is where nearly everything happens. Those pairs played 68% of all the games, a median of 22 games each across a median of three different days. The pairs that never came back played a median of two.
So for a 1v1 game with a friend, "is it fun?" is the wrong test. Almost everything is fun for one evening. The test is whether anything pulls you both back tomorrow.
A long first night predicts a second one
One pattern stood out. The longer a pair's first sitting, the more likely they were to come back:
| Games in the first sitting | Pairs | Came back on another day |
|---|---|---|
| 1 | 80 | 16% |
| 2–3 | 64 | 17% |
| 4–6 | 26 | 35% |
| 7 or more | 47 | 32% |
Pairs that played four or more games the first night came back about twice as often. This is a correlation, not proof: pairs who already like each other's company will both play longer and come back more. But the jump happens at four games, not at forty, and that is useful. One round is a demo. Four rounds is a rivalry with a score in it.
What makes a 1v1 game with a friend last
Put together, the numbers point to a short list.
- Short rounds. The games that pairs played most often take between under a minute (hot potato) and about three minutes (a sea battle) from one start to the next. A round you can finish while the kettle boils gets an "again". A twenty-minute round gets a "maybe tomorrow".
- A clean finish. A board that ends in a clear win or loss, with nothing left to argue about, makes the rematch an easy decision.
- More than one game. Most long sittings switched games. One game wears out in an evening; five games give a night shape. The loser picking the next game is a good rule.
- A score that carries over. A running head-to-head record turns tonight's last game into tomorrow's reason to play. "7–5 to you" is a sentence that demands a reply.
- A way to play when you are not both free. Live sittings need two free people. A challenge your friend can answer later keeps the rivalry alive on the nights you cannot sit down together. We wrote about that in games for a friend who is never online when you are.
How to use this tonight
If you are picking a 1v1 game to play with a friend, do three things. Agree to play at least four rounds before anyone decides whether they like it. Pick two or three short games rather than one long one, and let the loser choose the next. And keep the score somewhere you will both see it tomorrow.
Who goes first is the one argument not worth having. We counted that too, and across 579 games it was almost exactly a coin flip.
