How Many Rules Can You Recall? Biss 20!

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 it weren't 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.

Biss 20 is a fast and fun party game that tests your concentration and short-term memory:

1. Count: Continue the sequence of numbers from 1 to 20.
2. Memorize: Every time a new number or situation arises, Fritz sets a new, mandatory rule (e.g., instead of the number 7, you must say "Moooo!").
3. Don't Slip Up: The one who forgets the new rule or applies it incorrectly loses the round!

Remember it, say it, and beat Fritz in the memory battle!
