INSPIRATION

I always think of using Appian to build something interesting rather than business process management related application as what most of us do.

INTRODUCTION

The application is basically just a Sudoku puzzle game. Details are attached as document as part of the submission. No database or customised plugin are involved in this application.

CHALLENGES

The challenges I ran into is that to generate the puzzle(numbers) in Appian. My initial algorithm took me about 3-5mins to generate the numbers. Now, it takes less than a min to generate the numbers after some modification on the design and algorithm. Out of 10 attempts, there might be 1 case when the numbers generation takes more than a min. In this case, the process will stop the number generator and use the pre-load numbers. This is to avoid long loading game time which provides bad customer experience.
