Three opponents, each running the scripted strategist: the same baseline the network was cloned from, the one that holds 0.469 against naive play. Beat the last combination or pass; bombs beat everything; first out goes up.
The rules, briefly
How to play
Combinations: singles, pairs, triples, full houses, straights of 5+, consecutive pairs and triples.
Order: 3 lowest … A, then 2, then the jokers.
Bombs (four or more of a kind, straight flushes) beat any ordinary combination; bigger bombs beat smaller.
Pick cards to raise them; the play button names what you’ve selected. When everyone passes, the trick clears and the last player leads fresh.
