How a game of Uno against bots works here: seating them, what they can see, how they decide, and what they leave to you.
Uno here seats two to ten. Open a table, and in the lobby press "Add an opponent" once for every bot you want. One bot is a quick two-player game, where a reverse works as a skip; three or four is the family game most people know. Only the host can seat a bot, and only before the first hand.
The one table rule is the length of the match: 200 points for a short one, or the official 500. Every bot sits down with a name and a tag that says bot, so you can always tell who at the table is a person.
Its own hand, the card on the pile, and how many cards everybody holds — the same as you. The hands are kept on the server, so a bot cannot see your cards, and your browser is never sent theirs. Every card a bot plays goes through the same referee as yours.
Bots take about a second over each move so that you can follow what happened. Skips and reverses from the bots before you are shown on the table as they land.
A bot plays its action cards first, then its number cards, and holds its wilds until nothing else fits, because a wild is the only card that always plays and costs 50 if it is caught in a hand. When it plays a wild it names the colour it holds most of.
It always says uno when it plays its second-to-last card, so you will not catch a bot out. When a bot is hit with a wild draw four, it challenges about one time in three. And when it cannot play, it draws one card and plays it straight away if it fits.
Because a bot names its longest colour, the colour it chooses tells you what it is holding. Keep cards of the other colours for when that bot is close to going out, and play a colour change against it rather than for yourself.
The wild draw four bluff works about two times in three against a bot, but a wrong one costs you four cards. Bluff when the bot after you is nearly out, not when you have a comfortable hand. And remember that a bot never forgets to say uno — the call to watch for is from the people at the table.
Invite friends with the code and let bots fill the rest of the table. Seats go round in the order people sat down, bots included. If somebody leaves in the middle of a hand, a bot plays their hand from then on; if their connection drops, their seat is held for twenty-five seconds, and the site plays it only until they come back.
Between hands the next deal starts by itself after a few seconds. If every person at the table leaves, the bots stop.
