A brainteaser with 255-degree flexibility that clicks, folds, zig-zags and coils as you solve it! The cards show you which pattern to try next, but watch out – the more you configure, the harder the patterns become! Coggy also features a different kind of puzzle on the back, so there are two ways to play. A tactile puzzle that challenges the brain while engaging the hands, making it a great fidget toy as well. 40 pattern cards included, 4 levels of difficulty, and a chain of gears that extends to 14″ in length.
