The card game
Don't be the durak.
Get rid of every card before the others do. Whoever is left holding cards is the fool, the durak. Two to six at the table, podkidnoy or perevodnoy, against bots from beginner to grandmaster.
Podkidnoy or perevodnoy
Throw-in or transfer, everyone throwing in or only the neighbours, on 24, 36 or 52 cards.
Two to six at the table
A heads-up duel or a full table, the attack going round clockwise.
Bots that think ahead
Six levels. The strongest taught itself the game over millions of games against itself. The one below it imagines the hands it cannot see and plays each move out before it makes it.
At a table online, against people and bots, with a seat for you until you leave it.
