"Pin-Code" () — an educational spin-off designed to develop interest in inventing, programming and science in children from 4 to 14 years old. Initially, it was supposed to be done in flash-animation (such as the pilot episode "Rescuing the Departing"), but later this idea was abandoned and production began in 3D computer animation instead. The show airs on Channel One on Sundays at 8:45 at Moscow time. From January 18, 2015 to February 7, 2016, the new season of the series aired under the title "Leap to the Future".
