Domino is a game of chance and skill that can be played in many ways. The game involves a set of tiles called dominoes, which have an identity-bearing side with an arrangement of dots (called pips) and a blank or identically patterned opposite side. The value of a domino is determined by its pip count, with a tile valued higher having more pips. The number of pips on a domino also determines the number of points it can score in the game.
A player places a domino edge-to-edge against another, forming a line of pips in a straight or curved fashion. A domino is scored when a line of pips ends with either an empty space or a matching piece. Dominoes are often used for decorative purposes as well, forming lines that form pictures or grids and even 3D structures such as walls.
Historically, dominoes have been made from various materials, including bone, silver lip ocean pearl oyster shell (mother of pearl), ivory, and dark woods such as ebony, with the pips inlaid or painted to contrast against the color of the material. More recently, domino sets have been made from other natural materials such as marble, granite, soapstone, or stone; metals like brass and pewter; ceramic clay; or frosted glass. Some contemporary sets use more novel materials for added artistic appeal or increased durability.
In the West, dominoes are most commonly played in positional games where each player turns two or more tiles face down to make a line of identical or matching numbers. Each domino is normally twice as long as it is wide, and the pips are arranged so that one end of the piece has six pips while the other has none or zero pips. The most common Western domino set contains 28 pieces.
The game of domino has numerous variants, but the most basic uses a double-six set and is played between two players. To begin the game, the tiles are shuffled and placed face down in a pile known as the stock or boneyard. The players then draw seven tiles from the stock and place them on-edge in front of them, allowing each player to see their own.
Career mercenary Domino (Neena Dupree-Lopes) was once employed as the bodyguard of Milo Thurman, but their relationship was broken up when she joined X-Force. She later worked for the Hong Kong branch of X-Corporation and helped thwart John Sublime’s Third Species mutant organ harvesting movement. Domino later teamed with the time-traveling Cable and Garrison Kane to form the mercenary group Six Pack, and helped restructure X-Force when they were separated during the overlap between Earth and Reality-295.
Able to shift the laws of probability in her favor, Domino is a weapons expert and a superb athlete and martial artist. She possesses the ability to manipulate emotions, and can create and wield a staff that fires projectiles. She also has a psionic link with Copycat, who sometimes acts as her alter ego.
