Startspilleren flytter spillbrikken etter å ha kastet terningen.

Because Norwegian very often makes compound nouns by joining words together.

startspilleren = start + spiller + -en

• spiller = player
• startspiller = starting player / player who starts
• startspilleren = the starting player

This is extremely common in Norwegian. The same thing happens in:

• spillbrikken = the game piece / playing piece
• terningen = the die

English often writes these as separate words, but Norwegian usually prefers one compound word.

The ending -en is the definite article attached to a masculine noun.

So instead of a separate word like the, Norwegian usually adds the definiteness to the end of the noun:

• en spiller = a player

• spilleren = the player

• en terning = a die

• terningen = the die

• en brikke = a piece/token
• brikken = the piece/token

In this sentence, the forms are definite because the rule is talking about specific game elements already understood from the context: the starting player, the game piece, the die.

Norwegian often uses the present tense in instructions, rules, and general statements about what happens.

So flytter literally means moves, but in a game rule it can naturally correspond to English:

• moves
• should move
• is to move

depending on how you translate it.

The infinitive is å flytte = to move
The present tense is flytter = moves

This use of the present tense is very normal in board-game rules and instructions.

It is an infinitive construction meaning after having thrown/rolled.

Breakdown:

• etter = after
• å = infinitive marker, like to
• ha kastet = have thrown

So etter å ha kastet terningen means after having rolled the die.

This structure is used when one action is completed before another happens:

1. first: roll the die
2. then: move the piece

That is why it fits this sentence well.

Because ha kastet shows that the action is completed before the next one.

• etter å ha kastet terningen = after having rolled the die

This is more precise when the sequence matters. In a board game, the die roll must be finished before the piece is moved.

You may sometimes hear shorter expressions with etter å + infinitive, but etter å ha kastet is especially clear and natural when you want to emphasize that the first action is already done.

Yes. In Norwegian, å kaste terningen is the normal expression.

Even though kaste often means throw, in the context of dice it is the standard verb. English usually says roll the die, while Norwegian commonly says throw the die in a literal sense.

So:

• å kaste terningen = to roll the die

This is idiomatic Norwegian.

Yes, absolutely.

That version uses a full clause:

• etter at startspilleren har kastet terningen

This is also correct and means the same basic thing.

The difference is mostly style:

• etter å ha kastet terningen is more compact and typical in instructions
• etter at startspilleren har kastet terningen is more explicit

The infinitive version is especially useful when the subject is understood to be the same as in the main clause.

The basic word order is straightforward:

Startspilleren + flytter + spillbrikken + etter å ha kastet terningen

That is:

• subject
• verb
• object
• time/sequence phrase

So the sentence follows normal Norwegian main-clause order.

A useful thing to know is that if you move the etter phrase to the front, Norwegian uses verb-second word order:

• Etter å ha kastet terningen flytter startspilleren spillbrikken.

Notice that flytter still comes in the second position, before startspilleren.

Because rules and instructions often use the role or function instead of a pronoun.

So instead of saying:

• Han flytter spillbrikken ...

the rule says:

• Startspilleren flytter spillbrikken ...

This makes the rule clearer and more general. It tells you exactly which player the rule applies to, without depending on gender or on a previously mentioned person.

That is very common in instructional and rule-based language.
