Get your brain cranking! Crankity is a curious mixture of building and brainteasing. Build the challenge on the card, then fill in the gaps to engineer the solution. Each of the 40 mind-bending puzzles requires a specific combination of gears. If you can get them all to spin smoothly together - hooray! You've solved it! If they jam up and won't move - you'd better try again. Only the cleverest gear-head will have what it takes to solve them all! Recommended for 1 player, ages 6 and up. Made in China.
