Moving from one challenge card to the next, it's up to you to fold this connected collection of sixteen colorful gears into the perfect positions that match each image. Start out with the first card and it might seem easy. But keep on working through medium, hard, and extra hard - "Wait, if this color's here, then how can that one be way up there?" It's not long before your synapses are in a jam and you're forced to shift to a higher gear of thinking! And that's just with the color gears... Flip Coggy over to reveal gears of alternating black and white and then find one of the black and white challenge cards. With almost no frame of reference, you're sent clicking and folding into an intense trial-and-error conundrum!
