Template:Pfstart

Put this at the top of a variable-height playfield.

Usually, you'll have a

{{pfstart}}
one or more {{pfrow}} lines
{{pfend}}

Example

{{pfstart}} {{pfrow| | |J|J|J| | | | | }} {{pfrow| | | | |J| | | | | }} {{pfrow| | | | | | | | | | }} {{pfrow| | | | | | | | | | }} {{pfrow| | | | | | | | | | }} {{pfrow|J| |-|-|-| | | |i| }} {{pfrow|J|J|J|Z|-|S|L|L|i| }} {{pfrow|O|O|Z|Z|T|S|S|L|i| }} {{pfrow|O|O|Z|T|T|T|S|L|i| }} {{pfrow|G|G|G| |G|G|G|G|G|G}} {{pfrow|G|G|G| |G|G|G|G|G|G}} {{pfend}}
Code	Output

It is possible to show one preview by putting the next piece all alone in a 2-row-high playfield above the main playfield.

Or alternatively, with hold:

Or like this...

Or with letters:

yy

For a 12-block-wide playfield as seen in Tetrinet, use {{tnetrow}} in place of {{pfrow}}. For 14 blocks, use {{qprow}}. And we have mrow(11 to 21, 24 to 32, 36, and 48), though mrow12 and mrow14 redirect to tnetrow and qprow. These can be used to show something on the sides (border, next piece) or for games that have a wider playfield, rotation states, or pixel art.

For narrower diagrams with normal size blocks, use {{mrow1}} to {{mrow9}}. {{mrow10}} redirects to {{pfrow}}.

For larger blocks, use {{size16row}}. {{size16row2}} and {{width5row2}} are specifically designed to use special large images (that start with M) when single letters are used.

For letter diagrams, use {{ltrow}}. We also have {{ltrow16}}, {{10Ltrow}} (uses special images that start with E), and {{16Ltrow}} (uses special images that start with 9). The E and 9 images do not exist yet.

For narrower diagrams with larger blocks, use {{width1row}} to {{width9row}}.

For big TGM blocks, use {{size20row5}}, {{size24row5}}, or {{size32row5}}. {{size20row5a}}, {{size24row5a}}, and {{size32row5a}} are designed for special large images (starting with C, X, and F respectively) when single letters are used, but the images don't exist yet, so they are yet to be created.

Finally, smaller 8x8 block diagrams can be done with {{srow}}. We also have {{size3row}} to {{size11row}}. {{size8row}} redirects to {{srow}}. {{size12row}} redirect to {{pfrow}}.

Large and small blocks

size16row template sets size to 16x16.

There are M(block) images specifically designed for 16x16, so that it won't be blurry.
Width1row2 to width9row2 also use 16x16 images.
With size16row2 template, you can use them with single letters. Here is what it looks like:

Similarly, size10row sets size to 10x10. Also, srow sets size to 8x8.

And size10row2 uses 10x10 images instead.
