‘re watching a match and it gets super close, right? The score’s tied at 40-40 – that’s called “deuce.” Now, things get a bit more exciting because it’s not just about winning a point anymore, it’s about winning by two points.
Think of it like this: deuce is like a mini-game within the game. From here, it’s all about the “advantage” points.
So, once the score hits deuce, we start using the terms “Ad In” and “Ad Out.” “Ad In” means the server won the point after deuce, giving them the advantage. If the server wins the next point (the “Ad In” point), they win the game – that’s called “holding serve.” But if the server loses the “Ad In” point, the score goes back to deuce again!
“Ad Out” is when the receiver wins the point after deuce. The receiver has the advantage now. If they win the next point, they win the game. If they lose, it’s back to deuce.

Basically, it’s a back-and-forth battle until someone manages to win two points in a row. It’s like a little mini-tournament within the game.
And you know what? It’s super common to see scores like “Ad In” or “Ad Out” after deuce. It’s a bit confusing at first, but once you get the hang of it, it becomes pretty clear. It’s like a little code for the score that tells you who’s got the advantage.
Here’s a handy table to help you visualize the whole thing:
| Score | Meaning |
|---|---|
| Deuce | 40-40 |
| Ad In | Server won the point after deuce |
| Ad Out | Receiver won the point after deuce |
Remember, it’s all about winning two points in a row after deuce. So, next time you’re watching a match and you hear “Ad In” or “Ad Out” called out, you’ll know exactly what’s going on!
Now, tell me, have you ever been in a tennis match that went to deuce? Did you win the advantage point? What’s your favorite part about tennis? Let me know!
