  3. I successfully installed it. But I have a question.
    Why every time I click left button on mouse to speed, the game freezes and when it’s back to normal I am already dead?
    I cleared my browser’s cache but nothing :/
    Is my laptop too old or what? It is 5 years old ”acer” and I don’t have windows 10 yet, is that a problem or something else?

  4. First time I ever used greasemonkey and tampermonkey. Never have installed any scripts ever before. this is the first time. History cache totally emptied from Firefox. Haven’t used Chrome on this computer until I installed it today to get the mod script working with SlitherIO. So very fresh installs of this mod.
    Script shows available in Firefox when the game is there, but the mod doesn’t do anything, just vanilla game.
    Chrome, tampermonkey shows nothing available when I go to play the game, just vanilla game.
    The advice given to many in the comments below simply don’t do anything. I’ve been at this for three days, taking my time step by step. The instructions are very clear, but simply do not work.

    • i just try it for you on a clear pc. to see what is wrong on first install. it is works good. if you can send us screen shot from your pc we can look for your problem.

      Thank you. What do you need screen shots of and how do I send them to you?

    • Anonymous

      Is there an email address I can send them as attachments?

    • Anonymous

      I have screen shots of GreaseMonkey with latest (and only) script for Slither.io
      shots of version and options, shot of start screen on this site with script “active” (but you’ll see does nothing)
      How do I post the screen shots. This page won’t allow me to paste or attach them.
      Do you have an email address or webpage for such things?
      Looking forward to figuring this out.
      Thank you
      PS do I have to join up to something for this to work? I couldn’t find anything like that.

  5. I’ve downloaded the script, how do i open the game so that i can literally play the game?

    • if you make your install you just need to join slither.io script will be activate when you join game

    So… it seems I have deleted all extensions per the instructions and installed Tampermonkey correctly and I see the Slither.io script listed in the Dashboard, but how do I actually play the game with the mods now? If I go to slither.io, it’s just the basic game with no zoom or skin choice or anything… what am I missing?
