The built-in timer changes colour, then beeps softly to let you know time's up. And with no loose parts to worry about, it's as easy to store and take along as it is to play! Your favourite word search game is now easier to play than ever! Includes Boggle case with electronic timer and instructions. For 2 to 4 players. Ages 8 and up.
