Gameful Design Heuristics

Although many gameful design methods have emerged recently, designers still lack standard evaluation methods for evaluating gameful design. For other established areas of UX, heuristic evaluation methods are commonly used. In usability engineering, heuristics are general principles or broad usability guidelines that have been used to design and evaluate interactive systems. Heuristic evaluation, in the context of usability, is the use of said principles as a usability inspection method by experts to identify usability problems in an existing design as […]


Designing for Motivation

Gameful Design (gamification) has been an increasingly popular approach for improving the user’s motivation and experience when interacting with digital applications. As a result, the number of gameful designers has been steadily increasing in the past years, as well as the reports of successful projects gamification projects. However, what I still miss is more reports of gameful design integrated to the general product design and development process. I have seen many gamification projects reported as stand-alone projects, separated from the […]


The peak-end rule influences enjoyment of games

The peak-end rule is a psychological heuristic that explains how people judge an experience largely based on its peak (i.e., its most intense point) and its end, rather on the whole experience. A research from the Universities of Saskatchewan and Canterbury and Autodesk sought to verify if this effect would influence player’s enjoyment of (casual) games. They manipulated the difficulty or balance of three simple games to vary the peak and end experiences, keeping the playing experience otherwise unchanged, and […]

However, in the last years, there is a particular growing interest in understanding users’ motivation to use a product, system, or service. This interest is spawned by observable low engagement rates: it is not enough to have […]
