Glossary of Terms

The language of London Blackjack explained

A

Ace

A power card that can be played on any card of its own suit, or on any other Ace. When played, the player must declare a new suit that the next player has to follow.

B

Black Jack

The Jack of Clubs (♣) or Spades (♠). When played, it forces the next player to pick up 5 cards unless they can counter it.

Bot / AI

A computer-controlled opponent that can be added to games. Useful for practice or when waiting for human players.

C

Counter

Playing a specific power card to defend against a pickup penalty. Valid counters to a 2 or Black Jack include another 2, another Black Jack, a Red Jack (to cancel), or a Joker.

Crazy Eights

The American name for the family of shedding games that London Blackjack belongs to. While similar, Crazy Eights usually lacks the complex stacking rules of the London variant.

D

Deck

The standard 52-card pack plus 2 Jokers used to play the game. When the draw pile runs out, the discard pile (except the top card) is shuffled to form a new deck.

Draw

Taking a card from the deck when you cannot (or choose not to) play a card from your hand.

H

Hand

The cards currently held by a player. The game begins with each player receiving 7 cards.

House Rules

The specific set of rules agreed upon before playing. LDN Blackjack enforces the most universally accepted "London House Rules" to ensure fair online play.

J

Joker

The ultimate wild card. Can be played on anything and becomes exactly what the player declares it to be (both rank and suit). Often used to counter massive pickup stacks by declaring it as a Red Jack.

K

King

A power card that reverses the direction of play. In a 2-player game, playing a King effectively skips your opponent, giving you another turn.

L

Last Card

A mandatory declaration a player must make when they reduce their hand to exactly one card. Failure to declare results in a penalty draw.

Lobby

The main menu area where players can create new game rooms, join existing ones via codes, or start Quick Matches.

M

Match

Playing a card that shares either the same suit or the same rank as the top card on the discard pile.

Mixed Stack

A sequence of different pickup cards played together. For example, playing a 2 on top of a Black Jack to create a combined pickup penalty of 7 cards.

P

Penalty

Cards that must be drawn from the deck, either due to a power card (like a 2 or Black Jack) or for a rules infraction (like forgetting to declare Last Card).

Power Card

Any card that has a special effect beyond just changing the suit or rank. In LDN Blackjack, the power cards are 2, 8, Black Jack, Red Jack, Queen, King, Ace, and Joker.

Q

Queen Trap

The rule stating that a Queen cannot be the final card played to win a game. A Queen must always be covered by another valid card during the same turn.

R

Rank Run

Playing multiple cards of the exact same rank simultaneously (e.g., three 9s). The suit of the final card played becomes the active suit.

Red Jack

The Jack of Hearts (♥) or Diamonds (♦). Used defensively to cancel out an accumulating pickup stack started by 2s or Black Jacks.

S

Shedding Game

The category of card games where the objective is to empty your hand of all cards. Uno, Crazy Eights, and London Blackjack are all shedding games.

Stacking

The act of responding to a pickup card with another pickup card, adding their values together and passing the cumulative penalty to the next player.

Suit

One of the four categories into which a deck is divided: Hearts (♥), Diamonds (♦), Clubs (♣), or Spades (♠).

Suited Run

Playing a sequence of consecutive cards of the same suit simultaneously (e.g., 4, 5, and 6 of Hearts).

T

Two (2)

A power card that forces the next player to pick up 2 cards. Multiple 2s can be played together, and they can be stacked upon by other players.

Two-Ball

Another common regional name for the game, alongside Switch and Blackjack.
