What it does

A 100 piece set where magnetic tiles form the frame and click-in plastic tracks, funnels and slopes carry steel weighted marbles down a run kids design.

Magnetic tiles build the frame; track pieces click in rather than relying on magnets
Spinning funnels, U-turns and slopes for varied runs
Five steel weighted marbles included
Compatible with other PicassoTiles and similar sized tile brands
Open ended, so runs can be rebuilt in new layouts

A good value way to add marble runs to magnetic tile play for kids 3 and up, and it works with other common tile brands. The trade-offs are that PicassoTiles are glued rather than riveted, so they are less tough than premium tiles, and younger children often need an adult to snap tracks together and get a run working.

How it compares
