Conclusion
It can be concluded that through our research, the existing online algorithm is considered very efficient and there are not many alternatives in which the efficiency of the program can be optimized further. Through the results we have collected, it is certain that each pin configuration for the puzzle has at least one unique solution. Furthermore, based on the data collected, strategies can be formulated that can help us solve the puzzle manually, without use of computer programmes. The main strategies that were formulated are the editing strategies and the application of the value system to allow a clear and defined solving process. This allows an individual to solve the Icosoku without the computer solver.
