Puntuamos en cada ronda.

It is the we form of puntuar. In this kind of sentence, it usually means we score, we get points, or we award points, depending on the situation.

So the exact English verb can change with context, but grammatically puntuamos is the verb for we.

Because Spanish often drops subject pronouns when they are not needed.

The ending -amos already tells you the subject is we, so puntuamos by itself is enough.

• Puntuamos en cada ronda = normal, natural
• Nosotros puntuamos en cada ronda = possible, but more emphatic

You would add nosotros if you want contrast, emphasis, or extra clarity.

In this sentence, it is most naturally understood as the present tense: we score in each round.

However, puntuamos can also be the preterite form we scored. Spanish sometimes has forms that look identical. Context tells you which meaning is intended.

Here, en cada ronda suggests a repeated or habitual action, so the present reading is the most likely one.

Because the written accent is only used when Spanish spelling rules require it.

With puntuar, some forms need an accent mark:

• puntúo
• puntúas
• puntúa
• puntúan

But puntuamos does not need one, because its stress pattern is already clear from normal spelling rules.

Here en means something like in or during.

So en cada ronda means in each round or during each round. It tells you when the scoring happens.

This is a very natural use of en in Spanish when talking about something happening within a stage, turn, round, or period of time.

Because cada is followed by a singular noun in Spanish.

So you say:

• cada ronda
• cada día
• cada semana

Even if you are talking about many rounds, the noun after cada stays singular.

Because cada already acts as a determiner, so you do not add la or una before it.

So Spanish says:

• cada ronda

not

• la cada ronda

This is the normal pattern with cada.

Yes. That is completely grammatical.

Both word orders are correct:

• Puntuamos en cada ronda
• En cada ronda puntuamos

The second version puts more focus on when it happens: in each round.

Spanish word order is often flexible, especially when you are moving an adverbial phrase like en cada ronda for emphasis.

No. Puntuar can be used in several related ways, such as:

• giving points
• scoring points
• rating or grading something

So it is not limited to games, although this sentence sounds very natural in a game or competition context.
