Galton's Goalie - Bell Curve

My kid spent a solid hour snapping the pieces together before he even realized it was a game about probability. The way the marbles drop through the pegs and pile up in that curve is weirdly satisfying to watch, honestly I caught myself playing with it after bedtime.

The bell curve mechanism actually works—watching the balls distribute into a perfect bell shape is oddly satisfying, and the assembly felt like a real engineering challenge.

Putting this together with my son was a great bonding experience—the step-by-step assembly really teaches how the bell curve works in practice. Even I learned something new about probability from playing with it afterward.
