Mobile Learning (also known as m-learning) and game-based learning (GBL) are two important elements in technology-enhanced learning. Mobile game-based learning relates to the use of mobile games to enhance the learning experience. The combination of the two elements gave birth to a new concept of an educational system called Ubiquitous Learning Game (ULG).

This has further been extended to enable students to utilize the games not only from a wide variety of mobile devices they may carry with them but also from desktop and laptop – making access to the games ubiquitous across time and devices. These affordances, combined with the infrastructure that provides teachers with real-time feedback and student data, make ubiquitous game-based learning a promising genre for implementation in the classroom. This is an extension of the domain of gamification combined with ubiquitous learning. ULG helps improve the engagement of students.

Example:
The UbiqGames project is the natural extension of previous efforts at MIT’s Scheller Teacher Education Program (STEP) lab to develop casual, mobile, and educational games. UbiqGames are a genre of mobile learning games based on casual design, which enables them to fit more easily into the formal school setting by being played in short, frequent bursts throughout the day.

A research paper also discusses gamification of English course using the u-learning system called HELLO (Liu, 2014).
