Advertising related to the game Adventure by UK developer Syrtis Software (Michael J. Evis).
This is one of the earliest known port of the mainframe game to a home computer system by a British developer; predating the Level 9 version by at least several months and other, less accurate translations, such as the one by Abersoft.
The game was produced by Somerset-based programmer Michael J. Evis, who had been writing and selling Nascom software as early as 1979/1980, as this Practical Computing small ad, from February 1980, shows...

In February 1982, Michael was advertising the game under his own name again; there is a mention of the software having been advertised by ANDCO in this advert, though.

The 32K version was advertised several times in Computing Today over the following months.
By January 1983, the price of the 32K Nascom game has been discounted to £8.95...
Both the 32K version of Syrtis Adventure, and what appears to be the 16K version are archived on the Nascom homepage. 16K / 32K. They had been mistagged as the Level 9 versions (Colossal Adventure) in the past... That's one of the issues when you've got lots of different ports of the mainframe game!

The Syrtis Software Spectrum version of Adventure gets a mention in this Mind Games column in Sinclair User, February 1984.
Link to Spectrum version
The Spectrum version was re-released by Micro Gold.
Note: The inlay states that the correct title of the Spectrum version is ZX Adventure 32K.
Micro Gold's Tony Rainbird (later associated with the software label of the same name) sought out and republished games previously advertised in the classified sections of magazines. From the date of this news article it seems likely the Micro Gold release dates from 1984...
