Editing Gnav (section)

== Rules ==
Each player receives a single card (or take a wooden piece from a bag) at random, and examines its value. If a player is dealt the Fool, they must knock the table to alert other players to this fact.<ref name="pagat">{{cite web | url=http://www.pagat.com/cuckoo/gnav.html | title=Gnav | publisher=[[Pagat.com]] | access-date=17 December 2015}}</ref> Players also receive equal supplies of [[counter (cards)|counters]]. Play then proceeds by turns, starting to the left of the [[dealer (card player)|dealer]]. In turn, a player may either choose to keep the card dealt, by saying "stand" (''"jeg står"''), or swap it with the left-hand neighbour by saying "change" (''"jeg byte"'').<ref name="pagat"/> Play continues until reaching the dealer, who has the choice of keeping the card dealt or exchanging it with the top card of the [[stock (cards)|stock]], [[draw (cards)|drawing]] another card if a Horse or House is drawn.<ref name="pagat"/> The dealer's turn ends the round.<ref name="pagat"/>

If a player attempts to swap the card held with one of the five highest cards in the pack (picture cards known as [[matador (cards)|matador]]), the exchange is prevented and another action ensues, depending on the matador held by the opponent:

* '''Cuckoo''': its holder says "Cuckoo!" or "Stop! Cuckoo!" and the round ends immediately.
* '''Dragoon''': its holder says "Chop!" (''"hugg av"''), and the player who tried to swap cards must pay a counter to the [[pool (cards)|pool]]. Play then proceeds with the player to the holder's left.
* '''Cat''': its holder says "Miaow!" or hisses like a cat and says "Change back!" (''"kiss, bytt om"''), the challenger pays a counter to the pool, and the game is reset so that every player has the card they started with.
* '''Horse''' or '''House''': its holder says "Pass the horse!" (''"hest vorbi"'') or "Pass the house!" (''"hus vorbi"''), and the exchanger must now swap with the player to the left of the holder (or with the top card of the deck, if the holder is also the dealer).

When the round ends, all the players reveal their cards and the one with the lowest loses the round. If two tie, they both lose. If the lowest card was the Fool, then both its holder and the player with the next lowest card lose. A losing player pays one counter to the pool and is eliminated if they have no counters left. The last player remaining is the winner.<ref name="pagat"/>

Instead of using counters, players may keep score using a chalk and slate. Players receive strokes (////) on the slate instead of paying counters to the pool and a player is eliminated on scoring an agreed number of strokes.
