Mem-Ex is a memory game like Simon played on a grid
Lines is a light-cycle game from Tron.
Transformer allows you to manipulate SCREEN$ files
Patterns creates lots of patterns.
From Your Sinclair review, (Recovered) of SAM Pack 1 courtesy of the YS Rock 'n' Roll Years YS78
This is actually a collection of three simple games, with a screen manipulator and pattern generator thrown in for good measure. On the games side, Pairs is a decent little version of Pelmanism, Mem-Ex is Simon played on a grid and Lines is that light-bike game from Tron. Patterns creates, well, a lot of patterns. Once you've seen them all, that's it. The Transformer, though, is the prize of the pack. It takes normal SCREEN$ files and through a series of icons and sub-menus, allows you to mess around with them in all sorts of weird and wonderful ways.
