Double arounds score twice the single value · case 01

Eight aces score 200 instead of 1000.

ROOT CAUSE

Arounds are multiplied by the count of complete sets.

VERIFIED REPAIR

A double around is worth ten times the single around.

Unsuccessful approach: Requiring more than two sets for the bonus scores a double around as a single.

Case contract

Input [hand, trump]. Arounds (one of the rank in each suit): A 100, K 80, Q 60, J 40; double around x10. Run in trump (A T K Q J) 150 each; marriages (K+Q same suit) 20, royal marriage in trump 40, but a K+Q used in a run is not also a royal marriage. Pinochle (JD+QS) 40, double pinochle 300. Return the meld total.

Why this case matters

Card-game engines, scoring apps and online tables apply this rule automatically on every hand.

Verification & scope

A bounded toy rule contract stated explicitly in the contract field; cards are two-character codes (rank, suit). Not a complete implementation of any published rulebook or casino table rules. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
