Minefield was published in 1982 for the Sinclair ZX81 by SYNCHRO-SETTE.

Minefield is a collection of two memory games:

MINEFIELD-1 The program starts with you being required to enter a number no lower than 2. This number represents the difficulty level where <2> is the hardest level. The game then proceeds with a little graphic man going from the top of the screen to the bottom, planting land-mines. He then re-traces his path and covers the mines. He repeats this procedure a number of times until you are asked HOW MANY MINES did he bury. The game ends with the correct answer being revealed.

MINEFIELD-2 Pretty much the same program as MINEFIELD-1 except the little man covers the mines as soon as he burys them so that they are only shown for an instance. Those with slow reflexes or poor eye-sight may have trouble with this one.

The other programs on the monthly magazine cassette tape were Spider-Dan, Twodates, Rorschach, Instring and Namesort.
