を marks the direct object of the verb.
Here, the thing being checked/confirmed is 勝利条件, so 勝利条件を確認する means that 勝利条件 is what gets confirmed.

• 勝利条件 = the victory conditions / win conditions
• を = direct object marker
• 確認する = to check / confirm

So the structure is basically:

[object] を [verb]

Japanese is usually an SOV language, which means the verb often comes at the end of the sentence.

So instead of English word order like:

Check the victory conditions

Japanese puts the action last:

勝利条件を確認する

This verb-final structure is one of the most important basic patterns in Japanese.

確認する is the dictionary form (plain form) of the verb.

This form is commonly used in:

• headings
• instructions
• labels
• game menus
• written notes
• casual/plain style

So in a game, guide, or objective list, 勝利条件を確認する。 can sound like a neutral instruction such as Check the victory conditions.

If you wanted a more polite sentence, you could say:

勝利条件を確認します。

If you wanted a more polite request/command:

勝利条件を確認してください。

Yes. Japanese very often omits the subject when it is clear from context.

So this sentence does not explicitly say:

• I check the victory conditions
• You check the victory conditions
• We check the victory conditions

It simply says 勝利条件を確認する, and the context tells you who is doing it.

Depending on where you see it, it could mean something like:

• Check the victory conditions
• I will check the victory conditions
• To check the victory conditions

Japanese often leaves this kind of information unstated.

It is a compound noun made of two parts:

• 勝利 = victory
• 条件 = conditions

Together, 勝利条件 means victory conditions or win conditions.

In this sentence, を attaches to the whole noun phrase:

勝利条件を

not separately to each part.

確認 is a verbal noun, often called a suru-verb noun. That means it can become a verb by adding する.

• 確認 = confirmation / checking
• 確認する = to confirm / to check

This is a very common pattern in Japanese:

• 勉強する = to study
• 説明する = to explain
• 予約する = to reserve
• 確認する = to confirm

So 確認する is not two unrelated words; it is a normal verb built from a noun + する.

The standard readings are:

• 勝利条件 → しょうりじょうけん
• を → o
• 確認する → かくにんする

A full reading would be:

しょうりじょうけん を かくにんする。

It can function as a full sentence, but in many real contexts it feels more like a brief instruction, menu item, or task description.

For example, in a game or app, 勝利条件を確認する。 might appear as:

• an objective
• a step in a tutorial
• a command option
• a mission note

Japanese often uses the plain form like this for short functional text.

Not exactly.

• 見る means to see / to look at
• 確認する means to check / verify / confirm

So 確認する has a stronger sense of making sure something is correct or understood.

For example:

• 地図を見る = look at the map
• 地図を確認する = check the map carefully / confirm the map details

In your sentence, 確認する suggests more than just glancing at the victory conditions. It suggests checking them deliberately.

Not grammatically in the strongest sense, but it can function like one depending on context.

確認する is plain non-past, not a formal imperative like:

• 確認しろ = Confirm it! / Check it!
• 確認せよ = Confirm it! (very formal/stiff)
• 確認してください = Please confirm it.

However, in manuals, UI text, and game instructions, the plain form often works as a neutral instruction. So even though it is not a direct imperative form, it may still effectively mean:

Check the victory conditions.

No, normal Japanese writing usually does not put spaces between words.

The standard way to write this is:

勝利条件を確認する。

Spaces are sometimes added in learning materials to make the structure easier to see, but they are not normally used in natural Japanese text.

Yes. Japanese nouns usually do not mark singular vs. plural the way English does.

So 勝利条件 could be understood as:

• a victory condition
• victory conditions
• the win condition(s)

The exact number is usually understood from context. In English, the translation often uses conditions because game rules commonly involve more than one requirement, but Japanese itself does not force that distinction here.
