1 8 1 8 1

info

1 8 1 8 1 (pronounced splits) is a 2D Esolang created by user:helpeesl on march 15th 2025.

commands

splitters

Splitters split the pointer in two and they go in the directions that it is labeled

Up r L l I g J v

Up-right r c { ( / j V

Right L c < F f _ e

Down-right l { < A ^ Q \ 

Down I ( F A , : ) 

Down-left g / f ^ , 7 }

Left J j _ Q : 7 > 

Up-left v V e \ ) } > 

instructions

Instructions tell the pointer what to do

powered

# gets user input and stores it in the pointer 

Unpowered: number 

Powered: string 

“ outputs the pointer and deletes it 

Unpowered: number 

Powered: string 

- flips the pointer’s value 

Unpowered: negation 

Powered: reciprocation 

= comparison 

Unpowered: stores the value of the pointer 

Powered: set the pointer’s Boolean to the pointer’s value is at least the stored value

Unpowered [ : adds the pointer’s value to the bottom of the deque

Powered [ : sets the pointer’s value to the bottom of the deque and removes it 

Unpowered ] : adds the pointer’s value to the top of the deque

Powered ] : sets the pointer’s value to the top of the deque and removes it 

non powered

? deletes the pointer if its false 

! flips the pointer’s Boolean 

* flips the pointer’s power 

0-9 without 7: multiplies the pointer’s value by ten and adds that digit 

functions

Functions can be defined anywhere that isn’t intercepting code

inputs
