Master Boy (1987, Z80 hardware, Covielsa, set 2) — About this game
The original Master Boy is a text-based quiz built around deciding whether a displayed answer is true or false. Choose a subject such as geography, literature, natural science or sport, then judge the answer rather than selecting from a long list of alternatives. Correct responses score more when made quickly, but mistakes consume the limited lives. In the two-player game both answer at the same time and share a life supply, so the same correct response can still produce different points. Learn the two decision buttons before trying to improve response speed.
