    GambleKit

    C++ Framework for slot machine games

    GambleKit is a free open-source C++ object oriented library for quick and easy building of slot machine and gambling games with reels and GUI management. It relies basically on declarative programming style, so the programmer needs simply to declare, for example at creation time, the basic layout and behavior of the game, and then leave the game flow, requiring as little additional intervention as possible. The project is welcoming contributors and feedback is appreciated! The next steps in development, by degree of priority follow documentation, more examples, slight code refinements and new features. Please let me know if you are using the kit and what new features would you find most useful. You're welcome at the discussions or to post me your inquiries
