At a party the tournament is part of the program, not the whole event, so keep it short: blitz 5+0 or even 3+2, 3-5 rounds. Such a mini-tournament takes 40-60 minutes - just the break between the table and the cake, so guests stretch their legs and compete.
Not all guests play, and that's fine. Gather those who want to, even if it's 4-6 people: a short tournament with a prize creates buzz, and the rest cheer.
Think up a symbolic prize - a medal, a nice bottle, the right to cut the cake first. At a kids' party a chess tournament is especially fitting: children compete eagerly, and the Swiss system keeps a beginner from facing the strongest right away.
If it's a birthday for a kid who loves chess, a tournament among friends becomes the highlight. Enter child guests as guests by name so you don't fuss with their phones.
Prepare the tournament in the bot @vibechessbot in advance: /create_tournament and the guest list by name. At the party you just press /start_tournament - and pairings are ready. Between short rounds, /next_round; at the end /finish_tournament announces the champion. No sheets, no arguments - more in the organizer guide.

Great, if the kid and friends like chess. A tournament among children with a symbolic prize becomes a highlight. Enter the child guests as guests by name.
Just a couple of minutes to create the tournament in the bot and enter the guest list. At the party you press one button and pairings appear.
Any symbolic one: a medal, a sweet prize, the right to cut the cake first. The point is the buzz and attention to the winner, not the value of the award.
The bot is constantly improved based on real tournaments. If you need a feature that isn't there yet, message the developers right inside the bot with the /support command. Many features appeared exactly because organizers asked for them, and useful ideas get added quickly.
At home - home tournament. For a crowd - chess party. Outdoors - chess outdoors. How it works in the bot - organizer guide.
