The project's aim is to develop both guidelines to develop games as well as create game ideas with guidelines how to use them.[br][br]The guidelines and ideas will include concepts for the processes based on our previous work and on new ideas. Several steps could lead to the production of a mathematical puzzles which consist of:[list=1][*]Developing an idea for a puzzle[br] [/*][*]Designing 3-dimensional models for 3D printing[br] [/*][*]Producing the model[br] [/*][*]Observe and try out the outcome testing whether the result is satisfactory or the process has to be repeated[br][/*][/list][br]The goals for a successfully developed puzzle are:[br][br][list=1][*]Increase geometric vocabulary[br] [/*][*]Actively use and understand guidelines by the JKU team[br] [/*][*]Use Soft skills to effectively collaborate[br] [/*][*]Improve creative problem solving [br] [/*][*]Improve the visibility of the JKU by taking home self-made items[br] [/*][*]Attract especially young people by using emerging technologies[br] [/*][*]Improve ability to connect abstract concepts and concrete items[br][br][/*][/list][br]
