Pip (counting)
Pips are small but easily countable items. The term is used to describe the dots on dominoes and dice, the symbols that denote suits and value of playing cards, as the name for the small seeds of some fruit, and sometimes as a synonym for "dot" in morse code.
Dice
On dice, pips are small dots on each face of a common six-sided die. These pips are typically arranged in patterns denoting the numbers one through six. The sum of opposing faces traditionally adds up to seven. Pips are commonly colored black on white dice, and white on dice of other colors, although colored pips on white dice are not uncommon; Asian dice often have an enlarged red single pip for the "one" face, while the dice for the game Kismet feature black pips for 1 and 6, red pips for 2 and 5, and green pips for 3 and 4.
Dominoes
Dominoes use pips that are similar to dice. Each half of a domino tile can have anywhere from no pips to six pips arranged in the same manner to dice pips. Some sets designed for more than four players may have more than six pips.
