My six-year-old spent a solid hour building a spiral tower before the marbles even came out. The green-tinted ramps are a nice touch and he keeps mixing the colors to make new patterns. Sturdy enough that it didn't collapse when his little brother bumped the table.

My son has been rebuilding the same tower for two weeks straight and still finds new ways to route the marbles through the colored ramps. The 49 pieces are sturdy enough that it doesn't collapse mid-run, which honestly surprised me for the price.

The 49 pieces snap together tight enough that our towers don't wobble, and swapping the colored slopes around keeps the track fresh every time. We've rebuilt it as a spiral and a zigzag already.
