Indoor krolf - is that even possible?
Yes, it's possible, but it will never be the same as outdoor krolf.
And here in 2018 it's very new to us, so we haven't found our feet yet. There's a lot of experimenting and experience being gathered at the moment.
We play in sports centers for handball, basketball, badminton, tennis, volleyball and so on. The mallets are the same as for outdoor krolf, but you need to switch to other type of ball. Outdoor balls will run forever if you use them indoor. Therefore we are experimenting with tennis balls with sand inside and leather balls in different sizes.
For holes we try to use the holes already there for badminton and volleyball nets. They are smaller than outdoor holes, therefore we also use smaller balls as tennis balls or leather balls with same size as tennis balls.
The rules are the same as outdoor rules, except for size of balls and holes.
As you can see, we are in a very early stage with indoor Krolf, but we will try to keep you posted here on this page.
