In recent years, it has become clear that modern education is not currently equipped with the proper tools to fully support remote teaching. Virtual reality (VR) has the potential to make remote education viable in the future. Nevertheless, many teachers and students lack experience and familiarity with this technology, which poses a challenge to its adoption in education. In this paper, we introduce Puzzle Playground, a game that builds familiarity with VR by teaching object interactions through puzzles in an interactive experience tailored for educators. Players gradually learn VR interactions by completing various puzzle levels. A preliminary user study indicated that people who learned with Puzzle Playground grasped VR interactions faster than those who learned with printed or visual methods.
