What is a CAPTCHA?

A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a test to verify that a user is a human instead of a computer program, or “bot”. It stops bots from making user accounts and comments that spam other users, or “scraping” all of the content from a site in order to steal it for other uses.

What is wrong with CAPTCHAs now?

Most CAPTCHAs require the user to read and type in text. The text must be hard to read in order to be effective, so those CAPTCHAs are either annoying, or not difficult enough to stop bots. In any case, as more Internet traffic comes from mobile devices, typing turns off users. In short, people hate typed-out CAPTCHAs, and some users simply walk away.

Are other CAPTCHAs more secure?

Unfortunately, all typed-in CAPTCHAs are now being solved by bots to some degree. Some CAPTCHA alternatives are actually much easier for bots to solve than before! Once these alternatives become popular enough to be worthwhile for spammers to target, they will crumble.

What is FunCaptcha?

FunCaptcha presents a mini-game that blocks the bots while giving your users a few moments of fun. It’s a real security solution, hardened by experts and automatically updated to provide the best protection. Users complete these little games faster than other CAPTCHAs, with no frustrating failures and no typing. They work on all browsers and mobile devices. Visually impaired users can complete an audio challenge.

Does FunCaptcha work on mobile and all other platforms?

Yes. It is built on HTML5, with full support for mobiles. It works great with touch interfaces, and does not require any typing. All platforms used by a site’s customers are supported, including every kind of PC and Mac. A Flash version seamlessly appears for older browsers. In short, your users won’t be blocked.

What's the status of the service? Are you up and running right now?

If FunCaptcha ever fails to load properly on a web page, it will be replaced by a message explaining the problem. Go to our service status page to learn more about any problems on our end that may be at fault.

If the FunCaptcha is not set up properly by the website’s creator, it will be replaced by a message. If the problem is not on our end, it may be due to improper setup. Please inform the creator of the web site, but also feel free to contact us to let us know.

Is there audio accessibility?

Yes. We use the well-known “reCAPTCHA” service to provide an audio CAPTCHA for those who need it. We realize that many people find that one difficult to use, but it’s the only truly secure audio solution we have found so far. We hope to greatly improve service for the visually impaired as soon as possible.

What deployment methods are available?

Learn how to deploy on our setup page.


With our WordPress plugin, you can put a FunCaptcha anywhere you want it to appear on your WordPress site.


Our Contact Form with FunCaptcha Wix plugin is a quick and easy way to setup a secure method for your users to contact you.


We provide the PHP code to insert into your page. With only four lines, it’s as easy to drop in as other CAPTCHAS or ads.


Support for other deployment methods will be coming soon. Contact us to let us know what you’d like.

What do the stars do?

You earn stars as you complete FunCaptchas anywhere on the web. The faster you complete the CAPTCHA challenge, the more stars you get. Getting 5 stars means you play the games as well as we, the creators, do– and we have lots of practice!

For now, we are experimenting with the star system, so to be honest, don’t pay too much attention to your star count yet. The long-term plan is that your star count will increase each time you play anywhere on the web. Once you reach enough stars, you will get special rewards.

What is “Security Level” in the options?

You can change the security level in your site’s options. By default, FunCaptcha’s security level is Automatic, and you don’t need to do a thing. But here are some details if you want to know what’s going on under the hood.

If the security level is Automatic, security starts at the lowest, Standard level. That means that users do fewer challenges, but spambots also have less work to do to guess their way past the challenge. For most sites, this is fine. Most people will only need to solve two challenges, and almost no spambots will get through. The security level rises and falls automatically, adjusted by FunCaptcha’s monitoring system. If our system suspects that a user is a spambot, the security level for that user automatically rises to Enhanced level, described below.

The Enhanced security level makes users do a few more challenges. It’s still easy and quick for humans, but becomes much harder for spambots to get through. No spambot that we see attacking our many sites is capable of getting through the Enhanced level.

As a site publisher, you start off at the Automatic security level, which is probably your best option, so you don’t need to do a thing. However, if you wish, you can adjust your settings so security remains always at a particular elevated level, and won’t adjust automatically. For example, you can assure that all of your users (and all spambots!) will always play at the Enhanced security level. You can change this setting for any domain listed on your account page. If you use our WordPress plugin, you can also use the plugin settings page. (If these two places don’t have the same security setting, the more elevated setting of the two will prevail.)

What are the “Trial Features” in the options?

In your site options you can allow or deny “Trial Features”. If allowed, we will try little experiments that aim to improve FunCaptcha or learn more about how it is used. We will only try out things that we think will lead to a better experience, so there should be no downside for you to allow them. But if you want to make sure never to get any surprises, you can turn this option off. We hope you allow them, though– we really think they help improve the service!

I have more than one site. How do I put FunCaptcha on all of them?

Great to hear it! For each site on a new domain, you need a new set of keys. The first set of keys was easy– you got them as you followed the setup directions. Now you are ready to put FunCaptcha on your second site and maybe it’s not clear what to do.

Please visit the setup page and see the section for your site’s technology. At the bottom, look for the section “I have more than one site. How do I put FunCaptcha on all of them?” That will give you easy instructions tailored for your site.

What is the popup (or lightbox) mode?

“Inline” mode will show FunCaptcha on your page as part of your form. The “popup” (aka “lightbox”) mode will show FunCaptcha only after the user submits the form. Popup mode tends to result in even better user conversion rates. See an example of popup mode below and on our registration page.
