隠し矢印パズル | ポケットウッドブレインティーザー

Took this to a coffee shop and watched three friends pass it around for twenty minutes before anyone cracked it. The four interlocking pieces are cut cleanly enough that you can feel the solution click into place. Genuinely tricky for something that fits in my pocket.

The four wooden pieces fit together so snugly that I kept second-guessing which way the arrow actually pointed. Took me about twenty minutes the first time, and I've handed it to three coworkers since who all got stuck just as long.

This little four-piece puzzle has lived in my jacket pocket for two weeks now, and I still can’t stop fiddling with it during meetings. The handcrafted wood feels smooth and solid, and that moment when the arrow finally reveals itself is genuinely satisfying.
