Arrangements

Arrangements, Shapes or Forms are when Numberblocks switch shapes. For example, 4 is mostly seen as a 2 by 2 square, but he occasionally appears as a tower (1x4) or other shapes. This page lists out all arrangements as seen in the official show (and other official content such as apps or social media).

Rules

Please read before editing this page!

1. NOBODY CARES about face placement. The only thing that matters is the SHAPE.
   • COLOR PLACEMENT DOESN’T MATTER EITHER. For example, a square Nine with its colors going horizontally has the same arrangement as its colors going vertically. Same applies to numberblocks which differ from the usual color scheme (e.g. the blue Eleven that appears when Twenty-Two splits in half).
   • Same thing applies to compound Numberblocks, unless you're talking about their components.
   • Same also applies to the "Ten Borders" (the thick border to group ten blocks for larger numbers)
2. DON'T TRY TO REMOVE THE SUBSECTIONS OF FOUR AND FIVE'S SECTIONS.
3. DON'T REMOVE THE SCROLL BOXES EITHER.
4. IF YOU VANDALISE THIS, YOU ARE BLOCKED FOR LIFE EVEN IF YOU HAVE AN ACCOUNT.
5. Some Numberblocks can make shapes that are not made out of cubes. Those go in the “Other Shapes” category.
6. Some Numberblocks can make (or have made) shapes that are separated, and thus do not count as polynominoes. Those go in the “Separated” category.
   • The space between two separate blocks (the row with no blocks) is denoted by "+0".
7. Make sure your photo is CANON. However, it is okay to rotate a shape, but ONLY if you’re really desperate.
   • This rule is EXTREMELY IMPORTANT. Make sure that your picture IS canon or else you could end up like this guy.
8. If it's bolded then that means the arrangement requires precise timing (i.e. they could only be seen on one or two frames in the process of changing shape). If it's italicized the picture was rotated.
9. You can edit out some extra Numberblocks with any art program. Yes, even MS Paint.
10. Don't add codes unless you know what you're doing. If you want to learn how to use the code CORRECTLY, look for TSRITW’s tutorials down in the comments or in one of his blog posts.
11. Do not add sections for Numberblocks that only appeared in one episode with one arrangement, like Forty-One or One Thousand.
    • Do not add Numberblocks that haven't appeared yet either. Only add them after their debut episode aires properly.
12. If a Numberblock bigger than 10 can be separated into $10x+y$ with a straight line and $y\leq10$, it counts as a "X Tens and Y" shape and should be named so, along with the other name.

    

    FYI, this is what the "X Tens and Y" shapes mean. So 11 is "Ten and One", 12 is "Ten and Two", 21 is "Two Tens and One" and so on.

    • For example, the compound Twenty-One in I Can Count to Twenty should be named "Two Tens and One", or "Twenty and One".
    • The "Tens and Ones" shapes also apply to those folded (i.e. 5 blocks tall). These should be called "Low X Tens and Y".

      

      This is a "Low X tens and Y" arrangement.

13. Arrangements only seen as a compound go into the "Compound Only" subsection of the figured-out Numberblock's section.
14. Sometimes, multiples of Ten (10) can rearrange while being a part of a Compound Numberblock. They go into the "Component Only" subsection.
    • Don't add them if they are seen independent.
15. If an arrangement has a really long code, it can alternatively be described by using "Left-to-Right" code.
16. Diagonal shapes are NOT counted as separate arrangements. They are actually a rotated version of the arrangement.
17. Do NOT add arrangements not made of cubes or seperated arrangements which are only seen for a split second. They are only added when they're seen stable.
18. Do NOT add Arrangements with the wrong number of blocks, like this one.

How do I read arrangement codes?

Arrangement codes is a systematic way of describing how a numberblock's blocks are arranged, using a string composed of numbers, letters and symbols. Below shows the full list of components in an arrangement code.

component	meaning	Example	arrangement code
$n$	n blocks arranged horizontally (sideways).		$3$ (or $3\times1$)
$x\times y$	Rectangle with a width of $x$ and a height of $y$. In other words, '''y''' layers of '''x'''. For example, Eight's default arrangement is two blocks wide and four blocks tall, or in code notation $2\times4$.		$2\times4$
$L$	all blocks aligned to the LEFT		$(1\times4)\underline{L}+4$
$R$	all blocks aligned to the RIGHT		$3+\underline{1R}$
$C$	all blocks aligned to the CENTER		$\underline{2C}+4\times6$
$CL$	Centered, but slightly to the left		$(1\times2)\underline{CL}+4\times2$
$CR$	Centered, but slightly to the right		$2\underline{CR}+5\times2$
$cn$	means the leftmost block is at '''c'''olumn '''n'''. The letter "c" MUST be lowercase.		$2\underline{c}4+4L+2\underline{c}3$
$[>]$	One block is skipped.		$3+1\underline{[>]}1+3$
$[>n]$	n blocks are skipped.		$1\underline{[>2]}1+4$
$[nY]$	$n$ rows are skipped (i.e. they have no blocks). Omit $n$ if $n=1$.		$3+1R+2R+1C\underline{[Y]}1C$
Three Dimensions Everything is same as two-dimensional blocks, but with these new rules added for the 3rd dimension:
$x\times y\times z$	A solid cuboid with a width of '''x''', a height of '''y''', and a depth of ''z'' (3D shapes only). In other words, '''z''' 3D layers of '''x×y'''. Omit z if $z=1$.		$2\times4\times3$
$[B(x,y)]$	Move one layer back (for 3D blocks), and x blocks to the right and y blocks above the top block of the left-most column of the previous layer. You may omit the $(x,y)$ only if $x = y = 0$.		$1\times2\underline{[B(0,5)]}\ 1\times6$
$[B(x,y,z)]$	Same as the rule above, but move $z$ layers back instead of one. (which means $z-1$ layers are skipped)

Oh, the shapes the Numberblocks could make!
