Light up your opponents when they see your scores on the Viper Illumiscore Illuminated Dart Scoreboard. Attain the best visibility during your games, so you can see what your next shot needs to be. The specially designed pencils (included) will glow brightly when the board is lit. No more guessing and scratch paper! Clean up is a breeze, as the board wipes clean after every game. The scoreboard is powered by 4 AA batteries or an optional adapter for two convenient power options. Once you’ve mastered the art of standard Cricket and 01 games, the game manual can put a new spin on to old favorites.
