This research explores how primary school teachers use games to enhance pupils' learning and development of conceptual knowledge. The study employs an illustrative case study design; data was collected through interviews with thirty (30) teachers who were selected using purposive sampling technique. Twenty teachers had some knowledge of game-based learning, ten teachers, however, did not know anything about the concept game-based learning. The results show that the use of non-digital games of different kinds to engage pupils is common in the learning of Maths, English, and Science. Teachers ascribed positively that the integration of game-based learning motivates pupils to come to school, actively engages them in the learning process, helps pupils to easily assimilate lesson contents, makes lessons lively and fun, and builds collaborative skills amongst pupils. Inadequate resources, noisy classes, time constraints, large class sizes, the reluctance of some pupils to participate, and inadequate knowledge are challenges reported by the teachers.
