Numberblocks Wiki

Sixty, or 60, is a Numberblock made up of 60 blocks.

She is voiced by Teresa Gallagher.


Sixty has 60 light violet blocks with purple borders and violet limbs. Her face is similar to Six's but her eyes are much far from her mouth. She also has an array display because she is a super duper rectangle (12 factors).


Like Six, she likes dice and games.

As seen in Heroes With Zeroes, she also likes video games.
