How a game of Hearts against bots works here: seating them, what they can see, how they decide, and what they leave to you.
Hearts here needs three players and seats up to six. Open a table and press "Add an opponent" once per bot: three bots with you is the classic four-handed game. With three, five or six at the table the deck is trimmed by a two or three of diamonds or clubs so it deals out evenly — the hearts and the queen of spades are never taken out.
The one table rule is when the game ends: at 50 points or at 100. Only the host can seat bots, and only before the first hand.
Its own hand and the cards played to the table, and nothing else. Hands are kept on the server, so a bot cannot see what you hold — not even the three cards you pass it until the pass is complete, when they arrive in its hand like any other.
Bots play at about a second a card, so you can follow each trick. During the pass, bots choose at once and the table waits only for the people.
When passing, a bot gets rid of the cards most likely to cost it: the queen of spades first, then the high spades that could be made to take her, then high hearts. In the play it leads low, and when it has to follow suit it plays the highest card that will still lose the trick — getting rid of a king under an ace is most of playing hearts well.
When it cannot follow suit, it throws its most dangerous card, the queen if it still has her. What a bot does not do is count the cards that have gone, notice who is collecting hearts, or stop somebody shooting the moon.
Because the bots never watch what anybody is collecting, shooting the moon is far more realistic against them than against people. If you are passed strong hearts and high spades, the bots will keep ducking under your winners and throwing you their hearts.
Leading low spades while you hold none of the high ones is the classic way to force the queen out, and the bots do nothing to avoid it. Nor do they remember what you passed them, so there is no revenge to fear for the queen you sent left.
Invite friends with the code and let bots take the empty chairs. The pass goes left, right, across and then a hand with no pass, counted from where each player sits — and at a table of three, where nobody is across, it is just left, right and none.
After each hand everyone presses "Ready for the next hand"; bots are ready at once. If somebody leaves mid-game a bot plays their seat, and if their connection drops it is held for twenty-five seconds and handed back when they return.
