3 Design & Drill sets: 3 Different versions of this award winning game are available. What they all have in common are kids use a mini-size, motorized hand drill or a hand-held screwdriver to attach colorful bolts onto the board. They can create their own designs or follow the included patterns to make specific shapes, patterns, letters or pictures, dependent upon the theme. Just snap the included bits into the drill or screwdriver, grab a handful of bolts, and go. Critical thinking, design copy and fine motor skills are all reinforced. Sets also include: socket bit, Phillips head bit, 50 colorful bolts, and pattern cards to follow. Drill requires 3 AAA batteries (not included). Extra power drill also available.
