Background & motivation n n Millions of people around the world are fascinated by Acquire, which requires great dill of strategy and intuition and a bit of luck! In the second part of the project, someone (not us!) will implement a smart agent who can play the game by itself.

Projects goal To implement a software that allows playing Acquire online with other users. n n Players gathering. When group was formed the server creates the game and inspects the way the game being played.

Game Review § Originally released by Sid Sackson in 1962. § Board game based on the business of buying and selling hotel chains. § The hotels are represented by square tiles that are placed on a 12 by 9 rectangular grid.

Game Review (cont. ) § A player's turn consists of : -Placing a hotel tile. -Buying up to 3 shares. - Drawing a new tile.

Information card

More important aspects n Merging hotels. n Handling shares in merge chains. n Ending the game.

Previous versions There have been a number of attempts at computer versions of Acquire : § raw QBasic code (44 K), which requires QBasic to run. § compiled EXE file (123 K), which will run by itself on a PC. § PC-DOS version (175 K), which is active. § “ Power. Players” , for Mac users.

PC-DOS version

Project steps Step 1: Develop an application that imitates the game board and its rules and build a database to support the game. Tools: C++ (Win 32 Console Application). The program will be debugged and run on a single station. The design is based on 3 major layers.

Project steps(cont. ) Step 3: CLIENT/SERVER. Tools: Winsock. Using Winsock class and its functions, we implemented a TCP Client/Server program in order to create a platform for user/game interaction in a symmetrical (full duplex) mode.

Project steps(cont. ) Winsock provides all of the TCP service facilities in the following areas: § § § § Basic Data Transfer Reliability Flow Control Multiplexing Connections Precedence and Security
