In the page's words:

ComedySLAM since 2011 The Düsseldorf ComedySLAM is the classic of the laughter bar: there are 2 groups of artists per event. Each "slammer" will perform a 10-minute program in the first round.

For each group, the audience decides who wins by applause. The winners from the two groups compete against each other in the final. One wins. Nobody loses.

ComedySLAM was launched in September 2011, making it the first comedy competition in Düsseldorf. The shows are hosted by Michael Ulbts (https://www.ulbtsmichel.de).

*Note: the location is not barrier-free. Seating is mostly beer benches*
