dominoes is a family of tile-based games played with rectangular "domino" tiles. each domino is a rectangular tile with a line dividing its face into two square "ends". each end is marked with a number of spots (also called "pips", "nips", or "dobs") or is blank. the backs of the dominoes in a set are indistinguishable, either blank or having some common design. the domino gaming pieces make up a domino set, sometimes called a "deck" or "pack". the traditional sino-european domino set consists of 28 dominoes, featuring all combinations of spot counts between zero and six. a domino set is a generic gaming device, similar to playing cards or dice, in that a variety of games can be played with a set.

according to wang's student, robert berger,









































the domino problem deals with the class of all domino sets. it consists of deciding, for each domino set, whether or not it is solvable. we say that the domino problem is "decidable" or "undecidable" according to whether there exists or does not exist an algorithm which, given the specifications of an arbitrary domino set, will decide whether or not the set is solvable.









































in other words, the domino problem asks whether there is an effective procedure that correctly settles the problem for all given domino sets.
