A complete stand alone set or can be used to expand on existing run elements. Includes two cradle chutes, which means marbles can shoot off in four unpredictable directions. Will marble drop from one cradle to next or will it take an unexpected dive off the edge? Engineered so that with enough speed, the ball will continue to roll through. 

Includes: 

• 25 building blocks
• 16 run elements
• 2 special elements
• 2 marbles
• 1 base-plate

Suitable for ages 4+. Especially intriguing for master builders ages 8-12 years.
