TruckTalk
Outfit truck drivers with special, hands-free cell phones that allow them to indicate "free" or "not available." Then, while they're driving and on dull stretches of road, they can switch to free and accept incoming calls. They could be tech support, or just companions for lonely people, or offer counseling. It would be a way for them to earn extra money and keep busy.
MazeMove
A game where two or more people can shift rows like in those number-scrambler games, moving tiles in a maze and allowing them to go to different parts of it. They would have to collect various goals through the game and then escape.
Organic Tetris
Just like Tetris, but with higher resolution and organic pieces. Curves, odd shapes, and maybe even separated pieces. Maybe Alphatris? Letters of the alphabet? Or it could be modded. Anything you want! Little people, or animals -- like Noah's Ark! Fit all the animals in the belly of the ark. Whales and squirrels and snakes and cows.
