## Introduction.

Starting from C.Shannon's paper[1], game artificial intelligence investigators have developed computer games that can play against to human. Deep Fritz, Chinook, Othello, Scrabble game programs can be exemplified. Although all of these programs are strong, none of them are perfect and they cannot win unless the competitors make a mistake. Today game programs make progress fast in terms of graphic and visual quality. However, it is early to say the same thing for artificial game intelligence. Actually game artificial intelligence concept is not defined clearly. Game program developers and academicians understand different things from this concept. Academicians think about behaviors of the characters in the game when they consider the game artificial intelligence. On the other hand, for game developers game AI is used to encompass techniques broadly. Path finding, animation systems, level geometry can be exemplified to these techniques. There are significant differences between natural intelligence (human brain) and artificial intelligence[6-9]. Firstly, human can play different games reasonable by using his/her brain. A computer can play different games reasonable only if artificial intelligence for each game is produced. There may be some common properties of games, Allis [2] categorized games according to their common properties. But, these common properties do not save us from writing different computer codes for each game. Secondly, we cannot expect a human to play perfectly, human can make mistakes. In contrast, all computers are expected to play perfect. Actually for a computer to play perfect, game has to be solvable, has to contain no uncertainty and has to have an algorithm which is not NP-hard. For example, checkers is a solvable game[3,12]. In this paper we examine the domino game. With domino various games can be played and various mathematic problems can be solved [4-5,13,15,16]. The game we examine is "101" game. This game contains uncertainty and it is played with 4 players [10-11]. We examine the game in terms of three points. 1) Artificial intelligence 2) Networking environment 3) Visual Classic domino set consists of 28 dominoes (pieces). The height of each piece in the form of a rectangular prism is less than its other dimensions, and the front face of each domino is divided into two squares by a line. In each square the numbers from 1 to 6 are shown or empty. Back side of the dominoes is designed in the way that they cannot be distinguished from each other. Various games can be played with domino set. One of the most popular kinds of these games is 101 game. 101 game is played by two people or four people. In this article the four-person game is considered. The rules of the game are as follows: Around a rectangular table four players as A, B, C, D sits. A and C and B and D are partners. All pieces are mixed and distributed among the players as seven pieces to each player.
