Hacker is one of ThinkFun's popular stem toys for boys and girls, and was created by the inventor of other popular code games like On the Brink and Code Master. It's a coding board game that comes with 120 challenges of increasing difficulty, from beginner to expert, and is one of the best gifts you can buy for kids who like smart games and a challenge. Hacker is made with high quality components, and comes with a very clear and easy to understand instruction manual - you'll be able to play within minutes of opening the box. Like all of ThinkFun's games, Hacker is built to develop critical thinking skills. Playing through the increasingly difficult challenges will improve logical reasoning, spatial reasoning and planning skills, all through fun gameplay, and teach core programming principles.
