The Smoothwave Challenge is game built for use at trade shows. It’s intended to illustrate the effectiveness of a certain type of spinal pain therapy. After a player enters his name and starts the game, red and yellow balls which represent pain, appear at the bottom and move up the spine. The player must touch the gray leads in the middle while a red or yellow ball is underneath to eliminate the pain. The more pain ‘balls’ that are eliminated, the higher the player’s score grows. After playing through normal mode, the player is introduced to ‘Smoothwave mode’, where the leads have a much larger area of effect, so eliminating the pain ‘ balls’ becomes much easier. This shows how the Smoothwave product can be more effective in treating pain.
