    Also, make sure that you have the latest Flash Player installed on your web browser. You can check that by going to here:

    Google Chrome has a built in Flash plugin, so if you're still having trouble and using Chrome, try disabling the built in plugin by doing the following:

    1. Go to chrome://plugins (just type that into your Chrome browser URL field)
    2. Click the "+Details" button at the top right
    3. See how many Flash Player plugins you've got. If you have two, disable the one called "PepperFlash" and then restart your browser, log in again and play.
    4. If you've only got PepperFlash, disable that, then download the latest Flash player here: and install it.
  • If you’re using Google Chrome and are running into issues with our games loading up on your browser, this is because Chrome has now disabled the use of Flash Player, to only allow for it's built-in flash player, PepperFlash, to be used. To get Flash Player enabled again, please do the following:

    Enabling NPAPI in Chrome Version 42 and later As of Chrome Version 42, an additional configuration step is required to continue using NPAPI plugins.

    2. Click the Enable link for the Enable NPAPI configuration option.
    3. Click the Relaunch button that now appears at the bottom of the configuration page.

    Developers and System administrators looking for alternative ways to support users of Chrome should see this blog, in particular "Running Web Start applications outside of a browser" and "Additional Deployment Options" section.

    Alternatively, if you're finding that our games are becoming unplayable on Chrome, try using a different browser (perhaps Firefox) to play our games on.

  • How do I become Friends with someone?

    To become friends with someone you need to follow them on their profile page. When they follow you back you become friends. When you follow someone you see their updates in your Activity Feed, and when they follow you back they will see yours. You can also private message friends.

  • How do I send someone a Private Message?

    To send a PM you need to be friends with that person. This means you will need to follow the person and they will need to follow you back. This helps our users avoid unwanted spam messages.

  • I need my Mochi Games data transferred to my Ninja Kiwi account for SAS3 and/or BTD4

    Email with your request. Include your Kongregate username and Ninja Kiwi username and email.

  • I want to delete my account?

    Send an email from the email you used to register your account with to along with your NK username.

    It's very helpful for us to know why you would like your account deleted too.

  • I'm getting an error message when I try to activate Bloons TD 5 Deluxe

    Error 3006:

    This error means that your serial has run out of uses. Email with your Order ID and email address and we can add more uses on for you.

    Error 3007:

    This error means that the serial being used is not valid. The most common reason is that there is a space at the beginning or end of the serial which the game doesn't recognise. Double check for spaces and try again.

    If you've copy and pasted and checked for spaces, email into and we can help figure it out.

  • I'm having trouble with my Apple, Android or other mobile device game

    One helpful step is to turn your device off completely, then turn it back on and try the game again. A reset like this can fix many problems, but it can't fix everything.

    There are quite a few things that can stop apps working on mobile devices so email and include as much information as you can. The following in particular is very helpful to us:

    1. What game you're playing
    2. What device you're using.
    3. What operating system version the device is using
    4. A few sentences describing what you see

    Note: Most games store your data locally on the device. This means that unless you've made a backup yourself (iCloud for iOS or another app for Android), we recommend that you do not clear your app data before emailing in to check what the issue could be with us.

For any other issues or problems please contact our support department

Include the following for extra speedy help:

  1. Ninja Kiwi username
  2. The game you're having trouble with
  3. Your operating system (Windows 7, Mac OS X 10.8 etc.)
  4. What browser(s) you've tried
  5. A few sentences explaining what bug or issue you're seeing.
