how does the backend know the configuration for the minigame with just the authorization cookie? i thought the cookie is only for the authorization!

From the top down:

1. According to my (limited) knowledge of sequence diagrams, the two return cookie instructions at the beginning can be omitted, resulting in the extra lifeline-part being obsolete as well.
2. @LeviUniAcc if I understand the configuration part correctly, it is not the one you're thinking about: You're thinking about the global configuration, right? But in this case, it seems to be the player-specific one.
3. return <x> should always be able to be deleted. You don't mention explicit return values in a sequence diagram. Arrows that only reference their own lifeline then without any text can be deleted as well.
4. load configuratiion
5. Why can't calls end on the same lifeline?
6. Perhaps, when the player progress is sent to the Overworld Backend, there should also be an (asynchronous) call from the Bugfinder Backend to itself to update the player stats as well (even if it isn't needed exactly for the Bugfinder, as it is used as an example on how all minigame backends should behave)

To clarify the call from the Overworld Frontend to the Overworld Backend.
The Overworld Frontend sends a request to get the configuration from the overworld backend with the cookie attached. Then the backend identifies the user with the cookie and sends the overall and user specific configuration back to the frontend.

I think we leave the return values in the diagram till we surely know if they necessary.

Why can't calls end on the same lifeline?

I think because this is UML

[cdingm]

could you please rename the file to sequence-diagram instead of sequenz :D

[delvh]

I think you still forgot the arrow from the bugfinder backend to itself to save the results of each minigame run.

[madebyTimo]

Yes that's still on my Todo-List. I will add it this evening

[madebyTimo]

I specified the forwarding of the minigame configuration id like we discussed it and added the save of game runs in the minigame backend

It's after the deadline, no new reviews are present.
Let's get it finally merged.
