The Thinker Subscription Puzzle Box For Masters - Very Difficult Puzzles For Adults

Can you complete a Rubik’s Cube in record time? Do you laugh in the face of 2,000-piece puzzles? The Thinker Subscription Puzzle Box is for masters, meaning this is not your grandpa’s puzzle box (or maybe it is - if he was a savage puzzler). These groups of puzzles are level 4-5 (out of 5) challenges made for the most committed players, chosen from Kubiya Game’s most popular wooden mechanical puzzles. Let it be known: the difficulty is not exaggerated. At all. Brace yourself for some invigorating, deliciously maddening, head-scratching puzzles!

Free your mind! Start thinking outside the BOX!

At the beginning of each month, we'll send you a special package containing mechanical puzzles that we believe are worthy enough to be in your collection.

Whether you choose the 3-month, 6-month, or 12-month subscription, we promise you an amazing ride into our puzzle world! All you need is outside-the-box thinking and a love of puzzling!
