Speaker Andreas Norlén had promised to only offer the party leaders water to speed up the process when new speaker rounds started on Wednesday.
So far, the situation looks complicated to get a government in place - with red lines and demands from different sides. But is water really the best way to dissolve knots?
Top politicians themselves have some other advice on how to lighten the mood at a negotiating table when the situation seems deadlocked.
Minister of Justice Gunnar Strömmer (M) thinks that it is usually quite pleasant around the negotiating table.
- Step one is to make sure you get people there. And they struggle a little bit there on the other side with that. If you have succeeded in that, you should get the rest done, he says and adds:
- A good cup of coffee does no harm.
Elisabeth Thand Ringqvist has become a main character in the current government drama. The center party has a red line against V ministers in a government, while V does not want to support a government they are not part of.
So who is the C leader at a negotiating table?
- I am very long-term in my negotiations, says Elisabeth Thand Ringqvist, but offers a tip:
- Bring homemade buns.
And there is something that C and V can agree on - because even Nooshi Dadgostar believes in homemade coffee - and a little milk in the coffee.
There you agree with C.
- Well, about homemade? Something with rhubarb, I believe, says Dadgostar.
Once the V leader sits at a negotiating table, she says herself that she is "kind and accommodating".
- And very willing to compromise - but clear about my values and what we decided on.
However, MP spokesperson Daniel Helldén – who is also supposed to be part of the negotiations between the red and green parties – does not believe in cookies.
- Then people get a little tired. Better to drink a good cup of coffee or tea - then you can talk.
He does not want to reveal what he himself is like as a negotiator - but his colleague Amanda Lind claims that she has a large dose of stubbornness.
- It's a lot about starting from where you can come together with common visions, ideas - and start there. There will be a few things you don't agree on and where you have to fight a little. But the starting point must be to find a way forward that both parties can find good, she says.
The Center Party's education policy spokesperson Niels Paarup-Peterson does not believe that just coffee is enough.
- I believe in ordinary respect and honesty. And maybe an Old Dane. It could be good right?
But whoever is to lead the negotiations between V, C and MP has neither coffee nor alcohol as tips.
- Honesty works best. Coming up with foul play and emergency lies to reach profits is very short-sighted. Politics is about building long-term relationships and mutual trust for each other. Then honesty is the most important thing, says S leader Magdalena Andersson.
How has the past week affected the trust between you?
- It hasn't been the best week, you could say. It can get better.
The incumbent Prime Minister Ulf Kristersson has said that he is open to a "non-socialist" constellation of five parties - M, L, KD, SD and C.
In that case, it would be based on the Sweden Democrats agreeing to give up ministerial posts - which Jimmie Åkesson said no to. At the same time, C has a red line against cooperation with the Sweden Democrats.
Trusting each other and having a common direction of travel is how Kristersson says he has worked during negotiations during the four years with the Tidö collaboration.
- And to appreciate each other personally. Those are my simple tips. So I have untied knots where we sometimes thought differently but have a common idea of what we want to achieve.
L politician and police officer Martin Melin does not believe that the negotiation table is a place to lighten the mood.
- It's not the right time to be cheerful. You have to be quite firm at the negotiating table, so I don't think you should go on like that.
Is there anything you can have on the table then?
- Yes, you can have alcohol, he says.
