The moderate Braincracker—perfect for those who crave a bit more of a challenge. Six satisfying pieces to chew on, each one a little trickier than the last. Easy to pick up, humbling to hold, and harder to put down. Tightening your grip only makes the solution slip further from your hand.
 
Double-sided pieces maintain a steady brain workout that keeps you engaged and a little off-balance—like a cozy family holiday indoors: awkward at times, but always part of the fun.
 
Naturally beautiful, healthy, and simple to enjoy.
