1. Macintosh system, a small game, picture a tall rectangular town, at the top is a coliseum, on either side are shops and perhaps training facilities, it's a simple RPG type game.
2. Also Mac, I want to say it was called "Diamonds" or something like that, all I can remember are colored shapes, like diamons and spheres, and trying to either clear the board of them, or navigate a maze, perhaps a puzzle solving game.
3. There were several games that we had for AppleII on 5" floppies, one in particular was something like "Butterfly Rescue" or along those lines. I remember trying to save something from goblins or trolls, there were lots of little mini puzzles, one in particular was trying to catch shapes in a truck.
