This section gives you an opportunity to play interesting games such as Sudoku
or solve puzzles such as Magic Square. At the same time you will learn how to
implement similar games or applications. All games are implemented using basic
OpenRules tables and/or Rule Solver.
The interactive graphical interface is implemented with
OpenRules
Forms.
Have fun playing the games and at the same time learn how to implement these games within Excel only. Each game is accompanied by implementation notes and the proper Excel files - look at these files to learn how easy to represent complex logic using a combination of rules and constraint programming. |
