Dogrywka zmieni punktację i ranking.

Because zmieni comes from the perfective verb zmienić.

In Polish, a present-tense form of a perfective verb usually refers to the future. So:

• zmieni = will change
• infinitive: zmienić = to change (as a completed action)

Compare:

• zmienia from zmieniać = is changing / changes (imperfective, ongoing or repeated)
• zmieni from zmienić = will change (perfective, one completed change)

So this sentence talks about a future result: the tiebreak/overtime will cause a change.

They are in the accusative case because they are the direct objects of zmieni.

The verb zmienić means to change something, so whatever gets changed goes into the accusative:

• Dogrywka — subject, nominative
• zmieni — verb
• punktację i ranking — direct objects, accusative

So the structure is basically:

[Subject] + [Verb] + [What will be changed]

Because punktacja is a feminine noun ending in -a, and in the accusative singular that ending usually changes to -ę.

So:

• nominative: punktacja
• accusative: punktację

This is a very common pattern in Polish:

• książka → książkę
• gra → grę
• punktacja → punktację

Because ranking is a masculine inanimate noun, and in the singular its accusative is usually the same as its nominative.

So:

• nominative: ranking
• accusative: ranking

This is normal for many masculine inanimate nouns:

• stół → stół
• plan → plan
• ranking → ranking

So even though it is an object here, its form does not visibly change.

Because it is in the nominative case and it agrees with the verb as the thing performing the action.

Here:

• Dogrywka = the thing that will change something
• zmieni = will change

So dogrywka is the subject.

Also, dogrywka is in its basic dictionary form here:

• nominative singular: dogrywka

Dogrywka often means an extra period, overtime, tiebreak, or playoff/extra round, depending on context.

The core idea is: something additional is played to decide the result.

So in different contexts it might be understood as:

• overtime
• extra time
• tiebreaker
• playoff round

The exact English translation depends on the sport or competition.

Because Polish has no articles.

English needs words like:

• a
• an
• the

Polish does not. So Dogrywka zmieni punktację i ranking can mean things like:

• The tiebreak will change the scoring and the ranking
• A tiebreak will change scoring and ranking

The exact choice in English depends on context, not on separate Polish words.

No, Polish word order is fairly flexible, because case endings show the grammatical roles.

The neutral, most straightforward order here is:

Dogrywka zmieni punktację i ranking.

But other orders are possible for emphasis, for example:

• Punktację i ranking zmieni dogrywka.
• Ranking i punktację zmieni dogrywka.

These alternatives can sound more emphatic or marked. For a learner, the original subject–verb–object order is the safest and most natural starting point.

Because i means and, and in a simple list or coordination like this, Polish normally does not use a comma before it.

So:

• punktację i ranking = the scoring and the ranking

This is just like English in most cases:

• A and B → no comma

Here is the breakdown:

• Dogrywka — noun, feminine, nominative singular
• zmieni — verb, 3rd person singular, perfective, meaning will change
• punktację — noun, feminine, accusative singular
• i — conjunction, meaning and
• ranking — noun, masculine inanimate, accusative singular (same form as nominative)

So the sentence is grammatically very compact, but each word has a clear role.
