Registramos la sala del juego de escape.

In Spanish, the subject is often left out because the verb ending already shows who is doing the action.

Registramos tells you the subject is we because -amos is the nosotros/nosotras form of registrar.

So:

• Registramos la sala... = We searched / We registered the room...

You could add nosotros for emphasis, but it is not necessary:

• Nosotros registramos la sala del juego de escape.

That would sound more emphatic, like we searched it.

It can be either one.

For regular -ar verbs, the nosotros form is the same in:

• present: we register / we search
• preterite: we registered / we searched

So registramos can mean:

• we search / we register
• we searched / we registered

Context tells you which one is meant.

For example:

• Ahora registramos la sala. = Now we search the room.
• Ayer registramos la sala. = Yesterday we searched the room.

Without context, the form is ambiguous.

Registrar has more than one possible meaning, so learners often notice that it feels a bit broad.

Common meanings include:

• to register
• to record
• to log
• to search thoroughly
• to inspect

In a sentence about a room, especially in a puzzle, police, or security-type context, registrar la sala usually means to search the room or to inspect it carefully.

So here, registramos la sala most naturally suggests that the room was searched carefully.

Spanish uses articles more often than English does.

Here, la sala means the room, referring to a specific room. In many situations, Spanish prefers the definite article where English might sometimes be more flexible.

So:

• la sala = the room

If you said just sala, it would usually sound incomplete in a full sentence like this.

Because de + el contracts to del in normal Spanish.

So:

• de + el juego → del juego

That is why you get:

• la sala del juego de escape

This contraction is mandatory except when El is part of a proper name, such as a title.

Literally, it means escape game.

It is made of:

• juego = game
• de escape = of escape / escape-type

In natural English, this usually corresponds to escape game or escape room, depending on context.

In Spain, people very often also use the English expression escape room directly. So juego de escape is understandable and correct, but escape room is also very common in real life.

Because la sala is a thing, not a person.

Spanish often uses the personal a before a specific person or sometimes a pet/animal with personal value:

• Veo a María.
• Buscamos al profesor.

But with objects or places, you normally do not use it:

• Registramos la sala.
• Veo la casa.

So the sentence is correct without a.

These words overlap, but they are not identical.

• sala often means a room, hall, or space used for an activity
• habitación often means a room in a house or hotel, and very often a bedroom
• cuarto is more general, but can sound more everyday or vary by region

In the context of an escape game, sala works well because it sounds like a functional activity space. That makes it a natural choice here.

Yes, very possibly.

In Spain, escape room is widely used. Depending on the situation, many speakers might say something like:

• Registramos la sala del escape room.
• Registramos el escape room.

That said, juego de escape is still understandable and grammatically fine. It can sound a bit more descriptive or more literal than the borrowed English term.

Yes, but the given order is the most neutral one.

Registramos la sala del juego de escape is a standard verb + object structure.

You could change the order for emphasis, but it would sound less neutral:

• La sala del juego de escape la registramos nosotros.

That puts extra focus on the room or on we.

For normal use, the original sentence is the most straightforward choice.
