UX (User Experience) design which is providing an affective value to the user is becoming more important. If we look at the affect research which has been conducted until now, it shows that the satisfaction research after the user uses the product and the research which defines the affective factor were majority. On the other hand, the study regarding the affective development process and the interaction factor that causes development has not been accomplished a lot. In order to understand the affective development process, a study on what kinds of causes make the each affective factor is necessary. For this study, I have analyzed the affective experience of `Oven Break` game which is recorded 10 million downloads from App store among the arcade games which is one of the representative game genres. I have understood the affective development process through this analysis. Based on this study, this paper aims to propose the directivity of the interaction design in order to offer the positive affect experience. On the basis of 33 affective factors which are extracted from the preceding research analysis, In-Depth Interviews of eight people were conducted. The observation was processed with dividing the user experience changes of `Oven Break` game into 7 phases, and the situation of UX development is classified as 4 types. In the process of the analysis, UX type formed from each situation is derived, and the interaction design strategy for the positive UX development of the arcade game is proposed.
