All this guide requires is a basic understanding of how to navigate the windows file app.

Super simple, all you have to do is open the files app, navigate to "This PC" then "Local Disk (C:)" from Local Disk (C:) go to "Users", from "Users" choose the user you are using (most people just have one, it will be the name of the user in the windows sign in)
From "Users" go to "AppData"
Then from AppData go to "Local"

and then finally, pick a file called "_5050"

inside this file you will see two items, one called "Stickers" and another called "Variables"

Open Variables in Notepad. scroll to where it says "[variables]" and you should see a line that says

points=*(some number).000000*

Now you can edit that random number to whatever you want, for the 1234 achievement, i set the points value to 617 (half of 1234). the first gamble you make when you open and close the game is guaranteed to win, so i changed the value, saved the notepad, opened the game again and gambled once, awarding me with the 1234 award


Hope this helps, enjoy the achievements!
