At six, a child holds attention on a single task for ten to fifteen minutes. So the tournament is built around that limit rather than around sporting fairness.
The whole thing runs an hour to an hour and a half including the prize-giving. Longer, and the children are tired before the tournament ends.
Usually not. A preschooler cannot budget time and does not understand why there is a button to press. The clock becomes an activity in its own right - they press it because it is interesting.
The workable version is one timer for the whole room: the arbiter sets ten minutes and announces the end of the round. Unfinished games are judged on the position or scored as draws - and that has to be said in advance, so there is no argument afterwards.
If you want to introduce clocks anyway, put them on one or two demonstration tables and explain them to whoever is curious. Full immersion can wait a year - a clock in the browser.
At the opening: two minutes maximum and three rules maximum. Everything else is explained as it comes up, at the table.
After that it is the adults' job. A child who leaves their king in check or forgets about a threat is not an offender - they are learning. Prompting is not allowed; correcting an illegal move is both allowed and necessary.
The basics for parents and teachers - the rules of chess and setting up the board.
About 75 minutes in total. The free play at the end is a good device: the children who enjoyed it keep going, and the parents take photographs and talk to each other meanwhile.
Everybody gets something, without exception: a medal, a certificate or at least a sticker. At this age the competitive result barely matters - what matters is the feeling of having taken part in a real tournament.
Categories are easy to invent: fastest move, most polite player, best student, prettiest game. They mean nothing formally and they work beautifully.
And tell the parents when the next one is. For this age group regularity matters more than level: once a month, three games, is the right rhythm - running a club for children.
Four or five, provided the children know how the pieces move. The format is different though: three or four short games, often with no clocks, with breaks between them and a prize for every participant.
Three or four of ten minutes each, with breaks in between. The whole event including the prize-giving fits into an hour or an hour and a half - beyond that the attention is gone.
Usually not: a child does not understand why there is a button to press, and the clock becomes a toy. It is simpler to run one timer for the room and announce the end of the round, judging unfinished games on the position or scoring them as draws.
Take them aside, give them water, bring them back after a few minutes, and be sure to say that everybody loses, even the champions. There is no need to make them finish: the game can be closed and the next round made optional.
No. Three at the opening is enough: if you pick a piece up that is the one that moves, we play quietly, and put your hand up when you finish. Everything else is explained at the table by the adult watching the game.

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.
Older children - junior tournaments. The whole family - family tournaments. Venues - a classroom. Rules - how to play.
