Two conversions of classic games for unexpanded ZX81 by Russell Marks
Shapestack T1K is a faithful conversion of the classic high speed Russian shape-sorting game, with full line scoring.
Lazyfrog is also a conversion of a well-known classic game, shoehorned into 1k.
Both games have fast loading and are recorded twice on both sides.
