bustingHand :: Card -> Card -> Bool Source

If you're holding the Minister, there's a potential to "bust out" -- to have to immediately leave the round because you're holding another high card.

getTarget :: Play target -> Maybe target Source

getValidPlays Source

Arguments

:: player	The current player
-> [player]	All other active players in the round
-> Card	The card they were dealt
-> Card	The card that was in their hand
-> [(Card, Play player)]	All valid plays

Return all valid plays for a hand.

If the hand is one that would bust out (see bustingHand) then returns an empty list.

playToAction :: (Eq target, MonadError (BadPlay target) m) => target -> Card -> Play target -> m (Action target) Source

Given a player, a card, and a choice of play, decide whether it's a valid action.
