Lorum rounds

These are contracts the online game already supports. Names shift by language and family; the aim of each round is what matters.

Avoid capturing the King of Hearts — the most dreaded card at many tables.

Objective: Do not win the trick that contains the King of Hearts.
Special rule: Some tables let the holder reveal the King before play. A revealed King is public and often doubles the penalty for whoever captures him.

Chaos face-down: cards stay hidden, and the Hearts King is still the danger.

Objective: Avoid taking the Hearts King while playing without looking at your hand.
Special rule: Cards stay face-down. You play a card at random; following suit is not required. If someone happens to follow with a higher card of the led suit, they win the trick.

Timing matters: the fifth trick is the one you do not want.

Objective: Avoid winning the fifth trick of the deal.
Special rule: House lists sometimes target a different trick number — 6th, 7th, or last — with the same idea.

One card decides the deal: keep the Acorn Jack — or Jack of Clubs — off your tricks.

Objective: Avoid winning the trick that contains the Acorn Jack (Unter).
Special rule: Often paired with the 5th trick on the same deal. French-suited tables use the Jack of Clubs instead.

Suits stop mattering: play the next rank, wherever it sits.

Objective: Empty your hand first by continuing a rank sequence. Leftover cards score against you.
Special rule: Lead any card to start a rank sequence (suits ignored). Play continues with whoever holds the next rank — Ace wraps to the lowest rank still in play. If nobody has it, the sequence clears and the next seat leads.

Cards add to a running total. Crossing 25, 50, 75, or 100 is what stings.

Objective: Play cards onto a running total without being the one who crosses the thresholds — or manage when you do.
Special rule: Any card may be played. Values typically count Ace, King, Queen/Ober, Jack/Unter and Ten; low cards add little or nothing. The round ends when the total reaches 100.

The classic avoidance round: every trick you take costs you.

Objective: Take as few tricks as possible.
Special rule: Follow suit if you can. Highest card of the led suit wins; there are no trumps. Some tables reverse this round into Get All Tricks.

Every major penalty at once. Nothing on the table is safe.

Objective: Survive a deal where tricks, penalty suits, queens, the Red King, and the last trick can all score against you.
Special rule: Penalties from several contracts apply in the same deal. Exact mix follows the chosen rule set.

Build ascending same-suit runs and race to empty your hand.

Objective: Be first to play your last card. Cards left in other hands score against them.
Special rule: A lead starts an ascending same-suit chain. The holder of the next rank plays immediately. Chains typically stop after four cards, on Ace, or when the next card is already gone.

The namesake layout round: build four suit piles and shed your hand.

Objective: Play legal cards onto the layout until your hand is empty. Finishing order usually decides the score.
Special rule: Each suit typically starts on a set rank (often Jack/Unter, or Ten in the Czech Tens variant). You must play if you can; passing when able is a fault at many tables. Some rule sets allow several legal cards per turn.
