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| | | | | }} {{pfrowblank}} {{pfrowblank}} {{pfrowblank}} {{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.

For a 12-block-wide playfield as seen in Tetrinet, use {{tnetrow}} in place of {{pfrow}}. Narrower diagrams are also available, to help with load times. Currently we have {{width3row}} to {{width6row}}.
