После перебора лег продолжается.

Because после normally takes the genitive case in Russian.

• Dictionary form: перебор
• Genitive singular: перебора

So:

• после перебора = after a bust / after the over-scoring

This is a very common pattern:

• после матча = after the match
• после урока = after the lesson
• после перебора = after the bust

Here перебор is a sports term, especially in darts.

In general Russian, перебор can mean things like:

• overdoing something
• going through too many options
• excess

But in a darts context, перебор means something like a bust: the player scores more than allowed, so that attempt does not finish the leg.

So this sentence makes the most sense in that specific context.

Here лег is a borrowed sports term from English leg.

It is used in games like darts to mean one unit or section of a match. So in this sentence, лег is the thing that continues.

A learner may also wonder if this is лёг (the past tense of лечь, he lay down). That is a good question, because Russian writing often omits the dots on ё.

But here it cannot mean лёг, because the structure of the sentence shows that лег is a noun, not a verb.

Because only перебора belongs to the phrase with после.

The structure is:

• После перебора = prepositional phrase, after a bust
• лег продолжается = main clause, the leg continues

So:

• перебора is in the genitive because of после
• лег stays in the nominative because it is the subject of продолжается

Because Russian uses продолжаться for to continue / to go on when the subject itself is continuing.

So:

• лег продолжается = the leg continues
• продолжает would normally need an object, as in he continues the game or she continues doing something

Compare:

• Матч продолжается. = The match continues.
• Он продолжает игру. = He continues the game.

In your sentence, the leg is what continues, so продолжается is the natural form.

Here -ся is part of the verb продолжаться.

It does not mean a literal reflexive idea like himself. Instead, it helps form the intransitive verb meaning to continue / to go on.

A useful contrast is:

• продолжать = to continue something
• продолжаться = to continue, to keep going

So in this sentence, -ся is just part of the standard verb choice.

It is:

• present tense
• imperfective aspect

Why imperfective? Because the idea is ongoing: the leg is still going on after the bust.

In Russian, the present tense of an imperfective verb often covers both:

• English continues
• English is continuing

So продолжается can sound like either, depending on context.

Yes. Russian word order is fairly flexible.

For example:

• После перебора лег продолжается.
• Лег продолжается после перебора.

Both are possible.

The version with После перебора first gives the time/sequence first: it emphasizes what happens after the bust.

That fronting is very natural in Russian.

It sounds natural in the right context, especially if people are talking about darts or another sport using the term лег.

Without that context, many speakers might find it:

• specialized
• a bit technical
• not immediately transparent

That is mainly because both перебор and лег are being used in a specific sports sense here.

Here it is the noun лег, the borrowed sports term.

A learner may worry because Russian often writes е where ё could appear in careful spelling. So лег on the page can sometimes be ambiguous.

But context solves it:

• лёг = he lay down would not fit with продолжается
• лег = the noun leg fits perfectly as the subject

So in this sentence, treat it as the noun лег, not the verb лёг.
