Numberblocks Wiki

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

She is voiced by Teresa Gallagher.


Sixty has 60 lavender blocks with indigo 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- big games! The "big" here can either mean long, grand, or literally big (life-sized): Sixty loves them all! As seen in Heroes With Zeroes, she does like video games and references them.

Episode Appearances


Sixty is six tens. She can make 12 rectangles, which is twice the requirement for being a Super Rectangle!
