This study is focused on the challenges in puzzle video games. Based on several previous studies, the researcher created seven different types of challenges in puzzle games. To study the key of challenging levels in puzzle games, three games were chosen, then walkthrough videos of these games were watched and challenges were noted and categorized into different types. The collected data showed that different puzzle games have different challenge types while abstract reasoning is the most common challenge in every puzzle game. The total challenge numbers and pacing in puzzle video games strongly depend on the design intention of the game. And The number of challenge types has no direct connection with difficulty. The category of seven types of challenges and the results of this study may bring reference and inspiration to future studies. It may also shed some light on puzzle game design.

In this research the aim was to create guidelines regarding design of levels in the RPG-genre. This was done relying heavily on a literary study and the work of others but also through exploring the standard of the gaming-industry today. The research results in a proposed set of rules and guidelines are aimed at helping a novice designer to successfully create game levels. Some emphasis on the RPG-genre has been made but the rules/guidelines proposed are adaptable to any game-genre.
