Eleven L's 木質拼圖 | 給青少年的挑戰性禮物

I've been stuck on this puzzle for three evenings now, and that's exactly what I wanted—the pieces are smooth-cut and the fit is deceptively tight. It's the perfect challenge to keep my teen off his phone for once.

Got this for my dad who loves brain teasers, and the eleven identical wooden pieces had him stumped for two evenings straight. The wood is nicely sanded with no rough edges, and the level 4+ rating is no joke. Figuring out they don't need to fill the box is the real trick.

My teenager spent almost an hour on this before getting all eleven wooden pieces to sit inside the box, and the pieces are sanded smooth with no splinters. It's tougher than it looks since the pieces are identical and don't have to fill the whole space, just fit.
