Royal Sweep: Cassino Remix

The classic Cassino fishing card game, you versus a thinking CPU. Play a card from your hand to capture loose table cards — either ones that match its value, or any disjoint groups that sum to it (a 9 takes a lone 9, and a 4+5, and a 6+3, all at once). Face cards capture only by pairing the same rank. Can't or won't capture? Trail the card onto the table. Clear the whole table for a sweep bonus. Each deal is scored — most cards, most spades, the 10♦, the 2♠, each ace, each sweep — and the first to 21 wins.
