Biss 20 (2020)

In Biss 20, you count from 1 to 20 together, with each player saying one number in turn.

Okay, that sounds simple! And it would be if not for Fritz the bat who keeps coming up with new rules that you need to remember — and just when you've remembered one rule, he's already waiting around the corner with the next one. How many rules can you recall?
