Though many of us are loathe to admit it, the simplicity of Minesweeper makes it a game that can take up inordinate amounts of time. But if you want to play without having to stare at a screen, Connect Design has released a series of scratch cards that let you experience Minesweeper with a coin instead of a mouse. The cards cost just $2 each, come in both easy and hard varieties, and they even come with stickers to represent the flags. Best of all, they double as postcards, making them a great way to keep in touch with friends who also happen to be gamers.
