쿠보로 마블 런

My kids have been at this for three hours and I haven't heard a single argument. The wooden blocks fit together snugly, so even the tall builds hold up when my youngest bumps the table. It's really a logic puzzle disguised as a toy.

My kids have spent hours building tunnels and ramps with these, and the marble rolling through the hidden channels never gets old. It really does make them think about how the pieces connect before they build, which I didn't expect from a toy.

The wooden blocks fit together so precisely that my 7-year-old can build a tunnel system without it collapsing halfway through. Watching her figure out how to route the marble through two levels kept her busy for an entire rainy afternoon, and honestly I got pulled into it too.
