This paper presents a mobile pervasive mixed reality game based on HoloMoL named Pervasive HoloMoL, where HoloMoL is a platform that helps us memorize different types of information by combining the method of loci memorization methodology and mixed reality (MR) contents delivered through Microsoft HoloLens. The HoloMoL is originally developed as an MR platform to develop information memorization enhancing applications, but we found that the platform can be used to develop broader applications beyond simple information memorization enhancements. In particular, multiple memorization methods used by different participants found in the initial experiment of HoloMoL can be useful as an effective game mechanic to increase a game's engagement. This paper reports an overview of HoloMoL. Then, how the multiple memorization methods in HoloMoL can be used in designing a mobile pervasive game as a primary game mechanic is described. Finally, we show some results and insights of the preliminary user study of Pervasive HoloMoL.
