This paper aims to highlight the problem-solving nature of video games by examining problem-solving techniques in the context of the educational game Zoombinis. Using screen-capturing software, the gameplay of an 8-year-old participant was recorded and analysed in relation to his strategies towards solving the implicit Mudwall problem in the game, from a global-local perspective. Findings indicate the development of techniques-'stepping-stone' and 'probable-exclusion'-that through Polya's problem-solving steps, the game's design and participant's experimentation, can be used to solve the Mudwall puzzle, illustrating such game's potentiality as a problem-solving environment.
