Cracking a Weird Combination Lock

RULES:

This rich boy made a weird combination lock!

Let’s rob him!

All I’ll say I know about the combination is:

it involves a large (at least 7 digits) prime number

Get one, and here's how we'll crack it:

Observe each digit individually–you may either

MULTIPLY, DIVIDE, ADD, OR SUBTRACT

Each digit from one of the other digits

YOUR GOAL: Get the final remaining digit

To be equal to the number of digits

That were originally in the number.

Once done, the lock is cracked! Good jorb!

Everything it was guarding is mine, go away now

DESCRIPTION:

The entire game is just that screenshot and the instructions. contained. You can download a high res version of it if you want, but it's just the same PNG--you just play it by following the rules, friend.

Made for Furry Game Jam 2023. A silly game about crime. I made this just cause I wanted to make something, and the game jam gave me a substantial enough excuse. Sorry if it's bad, I gave it the old college try.
