Rubik, the Amazing Cube (1983–1984) watch online

Rubik, the Amazing Cube is a 1983 half-hour American Saturday morning animated series based on the puzzle created by Ernő Rubik, produced by Ruby-Spears Enterprises and broadcast as part of The Pac-Man/Rubik, the Amazing Cube Hour block on ABC from September 10 to December 10, 1983 and continued in reruns until September 1, 1984. The Rubik half hour was broadcast in reruns as a standalone series on ABC from May 4 to August 31, 1985.

The program features a magic Rubik's Cube named Rubik who can fly through the air and has other special powers. Rubik can only come alive when he is in a solved state. The voice of Rubik, Ron Palillo, told TV Guide in 1983 that for the role, he spoke very slowly and then technicians sped up the tapes and raised the pitch in an Alvin and the Chipmunks–esque manner. Palillo said Rubik's giggle was very different from the trademark laugh of Horshack, his character on the TV series Welcome Back, Kotter, and that it was pretty "for an inanimate object". It was also one of the first American animated series to feature a mainly Hispanic and Latino American roster of characters, along with voice actors.
