Français - Chaucn reçoit 3 jetons puis 5 cartes d'une certaine valeur. A chaque tour, vous ajoutez une carte sur la pile, annoncez le nouveau total des cartes empilées puis vous piochez. Mais si le total annoncé est un doublé (11, 22, 33, ...) vous perdez un jeton!

Anglais - Double Down, first released as Lobo 77, is a simple game of playing cards to add to (or subtract from) a running total. Players must try to avoid creating a total which is a multiple of 11, or taking the total over 77. Chips are given out at the start of the game, and are lost as players fail to keep to these rules - the last player with chips remaining is the winner.
