I made a little free tool that will generate bingo cards for your watch party on election night. Stuff like "Angela Rayner holding a beer" or "Winning candidate cries" or "Swingometer malfunctions".
There are over 100 different possible suggestions in total, and you can make cards with 12, 16 or 20 bingo squares on them. It should take just a few seconds to produce enough cards for all your guests. All you need is a printer and some A4 paper.
