I'm going to have to go with a few oldies from my Macintosh.
-Battle Chess. It's chess, but the pieces fight each other when someone gets taken.
-Shufflepuck Cafe. Bascially air hockey for the computer. You use the mouse to control the paddle and beat opponents ranging from regular men to aliens.
-Klondike. It's Solitaire for Mac. It's called Klondike to set it apart from Canfield, another Solitaire game.
-Cairo Shoot Out. It's like the shooting gallery booth at the county fair and the targets are Egyptian symbols. "Walk Like an Egyptian" by the Bangles is featured in this game.
-3 in Three. One of my all time favorites. This is a puzzle/logic game where you are a number 3 tryirng to escape a prison inside the computer.
-Fool's Errand and At the Carnival. Both are from the same guy who wrote 3 in Three and both are also good puzzle/logic type games.
-WordTris. It's like Tetris but also like Scrabble. Put the letter blocks together to make words, which then get eliminated from the board.
-SimAnt. It's like The Sims but you're an ant colony. You learn a lot about ants too and get to experience every aspect of an ant colony.
-OutNumbered. Yes, it's a math game, but I thought I'd mention it here. You save a TV station from takeover by solving word problems, getting clues from them, and matching them up with clues from the robot, who gives you regular math problems.
All of these games are a bit old (they all came out in the late 1980s-early 1990s). Most won't work right on new Macs. Thankfully someone fixed me up with a program called vMac that lets me run them. Most of them are black and white but a few also play in color (some still work on my OS 9 iBook without vMac and they play in color).
