This showcase is one part of a game-based second-language (L2) learning environment. The design is based on game-based learning (GBL) and task-based language teaching (TBLT) approaches.

Based on the prior games in that learners identify numbers and prices, this showcase helps learners to acquire the skills to express units and prices. It is a first-person role-playing game (RPG) designed in a life-like scenario. Multi-modes within the game help learners progressively develop targeted communication skills.
