Sixty-Four, or 64, is a Numberblock made up of 64 blocks. She is an 8 by 8 square, and a 4 by 4 by 4 cube.
Sixty-Four first appeared in The Big One as a compound Numberblock, then in More to Explore, Eight draws Sixty-Four on the grid in the square temple.
Appearance
Sixty-Four has 60 lavender blocks with indigo borders and 4 lime blocks. On the back of her blocks, she has a black and white chessboard. She has square eyes for being a square, and thick eyebrows like Nine. Her eyes, mouth and eyebrows are blue-ish purple and her limbs are purple. Despite stating that she is a super-rectangle, she doesn't have an array display.
Personality
Sixty-Four's a square who invents things like her Time Machine and the Binary Boosters. As shown in Double Back, she's also pretty talkative. She also takes her own "life" to bring others' belongings back, as she used her eights to be hit up by the Blocktopus rather than Six and Two's dice.

Trivia
- Before it was revealed that her voice actor is Teresa Gallagher, fans thought she was voiced by the same voice actor as 100, Sharon D. Clarke.
- This is technically true, as in Double Back, she is voiced by Sharon D. Clarke.
- Even though she has 7 factors, she doesn't have an array display. This is most likely an error while making her rig, as it is stated in her debut that she's a super rectangle.
- Just like One and One Million, she is both a square and a cube, making her the second Numberblock to be both a square and a cube chronologically.
- She is numerically the third square and cube
- She is the only Numberblock with 7 factors.
- It is conjectured that the absence of the array display is likely because of the criteria for the rig just misses Numberblocks who has exactly 7 factors, and the criteria is perhaps like follows: “Super Rectangle” for those with 6 factors, and “Super Duper Rectangle” for those with at least 8 factors, and thus the “Sixth-powers” might be missed. However Thirty-Six and One Hundred also have an odd number of divisors, yet they have array displays. This may be because the rigs focus on Numberblocks with a composite amount of factors, and ignore Numberblocks with prime factors, or it could be a mistake.
- She is the only super rectangle to not have an array display (physical).
- Her drawing in More to Explore doesn't have eyebrows.
- She was mentioned in We're Going on a Square Hunt as 8x8, and then appeared later in The Big One as "60 and 4”.
- She shows an interest in technology because 64 had a role in that field.
- While Sixty-Four shows her cubic arrangement faceless first in Square on the Moon, she first physically mades her cubic arrangement in We Need Another Hero.
- She's the biggest Super Rectangle. (She is not a Super Duper Rectangle, as she has 7 factors.)
- She was the first of the 60s to be figured-out, but numerically and chronologically the second.
- She's the only female in the 60s to be figured out, beside Sixty herself.
- Sixty-Four is the first Numberblock in numerical order to be a cube, Super-Rectangle, Super-Duper Rectangle and Square.
- She, along with all the Numberblocks ending in 4, has eyebrows.
- She is the second Numberblock above 50 to be figured out in release date order, with the first being 55.
- She is the only physical sixth-powers (aside from One) that are figured out.
