Logic puzzle games like Sudoku are getting popular for they are flexible in playing time and space and are useful in education. For puzzles, difficulty is arguably one of the most important factors in problem design. A problem too easy is boring, yet a problem too hard is frustrating. Providing problems with adequate difficulty to avoid boredom or anxiety is thus an important issue. In this paper we rate difficulty level of Sudoku problems with human oriented, general difficulty criteria so that the method can be used to evaluate problems of most logic puzzles. Only few previous Sudoku difficulty research are based on real playing data and the rating methods are limited to Sudoku or at most, constraint satisfaction problems (CSP). We found that the proposed method, despite of its simplicity and generality, can sort Sudoku problems in an order similar to average player solving time, the player perceived difficulty.

 

“To Get Help, Please Press X” The Rise of the Assistance Paradigm in Video Game Design

The first generation of video games are known to be tremendously challenging. On top of the classic “easy to learn, hard to master” arcade games, the development of the domestic market saw the rise of more expansive and varied game worlds, in computer RPGs or adventure games. This added complexity is often synonym with a more steep difficulty curve due to the amount of information to assimilate early on. In this paper, we will try to understand how game designers have organised the challenge and complexity of their games through the development of assistance systems: tutorials, check points, adjustable difficulty, etc. The historical evolution of these systems supposes a major change in the way players are addressed by the medium, from the highly competitive environment of early days to the seemingly more cooperative attitude of contemporary games.
