Fast curves, clever levers, flexible tracks: This innovative marble run from Kosmos is the ultimate experience for marble run fans and beginners and an absolutely unique piece with every construction.

Review: Super coole Idee und lässt viel Raum für kreative Ideen. Hält aber je nach Oberfläche nicht so gut und manche Mechanismen sind schwierig zu realisieren für Kinder. Selbst meinem 8 jährigen musste ich mehrfach helfen…
Review: Ich habe das Set meinem 12-jährigen autistischen Neffen geschenkt, der Murmelbahnen liebt – und es war ein voller Erfolg. Das Starter-Set hat ihn sofort begeistert, und inzwischen hat er sich schon mehrere Erweiterungen dazu gewünscht und bekommen. Die Teile sind stabil, lassen sich gut anbringen und bieten genug Abwechslung, um lange damit zu spielen und immer neue Strecken auszuprobieren. Perfekt, um kreativ zu werden und gleichzeitig etwas Konzentration und Feinmotorik zu fördern. Als Geschenk absolut gelungen und sehr empfehlenswert für alle, die Spaß an Murmelbahnen haben.
