Proton is a retro-futuristic, self-contained, abstract strategy PocketBoardGame* for 1 or 2 players. It features an innovative design that utilizes existing manufacturing technologies, and is therefore very inexpensive, costing just $5 a unit. The 15 sliding tiles make up a dynamic gameboard which makes each game different. The game is so easy to learn that all of the rules, plus instructions for solitaire activities, appear on the back of the comfortably hand-sized plastic unit.

Lightweight and compact, Proton is the perfect go-anywhere board game. You can take it to the movies, the airport, or the great outdoors, and never lose any of the game pieces. Most games of Proton take about 5 minutes, so you can play it while standing in line or waiting for food in a restaurant. And if a game gets interrupted, you can put it in your pocket and resume it again (or not) with ease.

* The German language readily creates new words whenever new concepts require them, often by simply ramming several old words together into longer new ones. (Some examples I recall from Frau Benson's German class at Northwestern High School: blitzkrieg, literally "lightning war", for the new rapid attack strategy, and fernsprecher, literally "far speaker", for the telephone.) I've always thought this was sensible, and PocketBoardGame is the best way to describe the new kind of thing that Proton is, so I coined a word.
