The company Flamagas is mainly engaged in the production of lighters and cigarette paper and it was a distributor for Game&Watch in the 80's and 90's.

The game originally came from someone whose uncle was working for Flamagas back then. The uncle received two of the "Flamagas" Game&Watch, which he gave to two of his nephews. From there, on of the games went on to a Game&Watch collector.
