About this game
VGA Concentration turns a collection of colorful pictures into a memory game. Reveal two cards, remember where each image appeared, and find its partner. Bill Dedes designed this Alive Software game for both children learning to recognize patterns and adults who want a larger board. The novice setting has 16 cards; expert mode increases the field to 36.
The score begins at 100. You can select each card twice without losing points, but revisiting it again costs a point. Try to remember both the picture and its position instead of choosing at random. The Speed option controls how long a card stays visible, so a slower setting gives you more time to study it.
This is the original version 1.2 DOS shareware package, with its supplied picture libraries and documentation. Keyboard control is already selected: use the arrows to move and Enter or Space to choose. Press P to select a picture set, O for options or H for help. The extra pictures advertised for registered users are not included.
