Rules

2 to 7 players. Total rounds = number of players × 3. With 6 players that's 18 rounds.

• Up: deal 1, 2, 3 … up to max cards. Trump rounds — flip the next card after dealing to set trump.
• No Trump: max-cards rounds. (maxCards − 1 of them.) No flipped trump.
• NIL: one max-cards hand. Everyone tries to take zero books. No bids.
• Down: deal max, max−1 … down to 1. Trump rounds.

“Books” are tricks. Each player bids how many books they expect to win. Dealer bids last.

Missing your bid is called going down.

• Bid 0, take 0 = 10 pts
• Bid N, take N = N × 11 pts (e.g. bid 5 take 5 = 55)
• Any miss = 0 pts
• NIL round: 0 books = 25 pts, otherwise 0

In trump rounds the highest trump in a book wins. Otherwise the highest card of the suit led wins. You must follow suit if you can.
