How a game of Spades against bots works here: seating them, what they can see, how they decide, and what they leave to you.
Spades is four players in two partnerships, and partners sit opposite each other. Seats are taken in the order people sit down: the first and third player are one side, the second and fourth the other. So if you open a table and add three bots, the second bot to sit down is your partner.
In the lobby choose the target — 250 points or 500 — and press "Add an opponent" until the table has four. Only the host can seat bots, and only before the first deal.
Its own thirteen cards, the bids and the tricks as they are played. Hands are kept on the server, so no bot, including your partner, can see your cards. A bot partner knows your bid because everyone at the table does, and nothing more.
Bots take about a second per bid or card, so you can read what each one said before it is your turn.
A bot's bid is a count rather than a judgement: one for every ace and king it holds, plus one for every spade beyond its third. A hand with nothing at all is bid nil about half the time and one the other half.
In the play a bot leads low, lets its partner have a trick its partner is already winning, and otherwise takes the trick with the cheapest card that does. It does not play to set the other side, protect its partner's nil or avoid bags — it simply tries to win the tricks it can.
Treat your partner's bid as honest arithmetic: a bot that bids four has four high cards and long spades between them, not a feeling. Add your own count to it, and remember that it will not duck tricks to keep the contract exact — bags are your job to manage.
Your nil is on its own. When your card is winning a trick, a bot partner plays low and leaves the trick to you — which is exactly what a nil bidder does not want. Bid nil only when your hand really can lose every trick by itself.
To partner a friend against two bots, add one bot before your friend sits down and the second after, so your friend takes the third seat. The lobby lists players in seat order, so you can check before you start; a bot can be removed and added again to move it to the end.
After each hand everyone presses "Ready for the next hand". If somebody leaves mid-game a bot takes their cards, and if their connection drops the seat is held for twenty-five seconds and handed back when they return.
