Krunker Free KR script

a playwright automation to collect free kr

I wanted to write (for fun) a playwright script to collect free krunkies it automatically logs you in, checks if you can collect free kr, clicks the free kr button, waits for the ad to finish & clicks spin button.

It works about half the time.

I have spent way too much time on this and since i don't even really play anymore, i don't care to finish it. This started as a fun challenge but it's neither fun or productive anymore (atleast for me).

You are free to pick it up & get it to work

my only ask is, if you get it to work, submit a pull request.
DISCLAIMER: you will need pretty good knowledge of javascript, i used a bunch of async/promise stuff

Problems

• the playwright chromium driver somehow does not properly initialize krunker so it's unusable
  • the webkit driver does not even support WebAssembly
  • i had to resort to firefox - that's why it's about 5x slower than chrome
• krunker uses 3+ different ad SDK's for the free kr ads
  • Ad in play / full screen apps - auto-close, so they work well.
  • Google ads (popup video) - has to be closed with x button, but can close itself. works sometimes
    • these videos sometimes have a "This video will play with sound, click continue" popup
    • this popup is hard to detect but sometimes the script closes it sucessfully
  • Google image ads - have to be closed with x button (material design) almost never work
• krunker seems to randomly pick an ad SDK for each day, so the whole day you'll get the same SDK
• reporting of how many kr you spinned is unreliable
• you could just wait a relly long time for the ad window to close itself, but then you usually get kicked by inactivity.
• there are a bunch of // TODO ... comments - you can see what i had planned, feel free to implement those.

Curent status

• unreliable. works on good days but fails more often.

FAQ

• is this legit? - yes. it does what a user would do, login, watch the ad, spin the wheel
• will i continue to work on it? - most likely no, unless krunker makes their ad SDK's more reliable.
• does krunker get money from the ads? - i see no reason they shouldn't i don't do anything wierd to the ads

Setup

1. clone the repo, npm i
2. create an accounts.json file: it should look like this:

   [
    { "name": "account1", "password": "password" },
    // ...
   ]

   you can switch between accounts (for testing) in the last async function, on the line:

   const _creds = credentials[0] // change this number to change the account
   

3. (optional) set debug = true in the top of main.js to see what it's doing
4. run npm run start
