The loopstring, or l-string, is a string of unstereotyped pencils. Technically, l-string is a sesquilinear random coiling* of a 1-brane (which is) concatenated to and from specified reading frames (egg and epp), and subject to certain conditions (such as being gameplay-compliant). The string may be open🔓 or closed🔒, but is closed by default (hence the term 'loop'). In fact, the main objective of each opus is to twist some variation of this object into a functionally unique fibor.As some measure of twistor space.

Notes (+): + In the context of the whole of string theory, the loopstring may colloquially be referred to as "toy string". We must be careful, however, to not confuse this "toy string" or its ludology (SL) with bosonic string theory (which is considered a "toy model" for which to introduce string theory education).

+ I named it "loopstring" from 'loopy quanta' plus 'superstring', even though both terms are misnomers.

An argument can be made that l-string is a rudimentary automaton. It is hypothesized that all games are (or any game can be) based on and around some primitive manifestation of this object. Hence, when we want to study the ludology of any phenomenon, we could start with a drawn l-string, and proceed from there.
