What to Do When CAPTCHAs Don't Work

Strategies to Use When CAPTCHAs Won't Submit

CAPTCHAs, those distorted letters and numbers that you often have to type before you can submit an entry form, are an attempt to separate legitimate entries made by real people from attempts to cheat using bots and scripts. However, as bots have become more adept at deciphering CAPTCHAs, programmers have responded by making them harder and harder to read. This can make it difficult, if not impossible, to get your entry form to submit successfully. Here are some tips to try if you just can't get a CAPTCHA to work.

If At First You Don't Succeed, Load, Load Again

Frustrated by CAPTCHAs? Here Are Some Strategies to Try. Hero Images / Getty Images

Have you ever opened a page with an entry form on it and not submitted it right away? If so, that could be a reason why you're having trouble getting the CAPTCHA to work.

One strategy to enter sweepstakes faster is to open a bunch of entry forms at the same time, then fill them out and submit them one after another. But when you do this, some time can pass between the time the first page is opened and actually fillling out the entry form.

Many CAPTCHAs have an anti-hacking feature that causes them to expire after a few minutes have gone by. And the CAPTCHA itself won't warn you that it is no longer valid.

So if your CAPTCHA isn't being accepted, the problem might not be with your reading or your typing, it may simply be that the code has expired. Try reloading the page to get a new code, then fill out and submit the form right away.

Llamas, Iguanas, and the Number 1

Depending on the font a CAPTCHA uses, a lower-case "l" as in "llama" can look exactly the same as an uppercase "I" as in Iguana or the number "1." Confusion between these three characters could be the reason why you can't get the CAPTCHA to work properly.

So if your CAPTCHA won't submit, check for these symbols. If it contains one of them, try the other possibilities to make sure that you're not reading it wrong.

O, Those Zeros

It can be very difficult to tell the difference between an uppercase letter "O" as in "Ocean" and the numeral "0" or zero, especially when the CAPTCHA has distorted the characters.

If you have been trying either the letter O or the number zero and the CAPTCHA won't go through, try the other.

Forget 2, 4 the Problem's 6, 8

The numbers "6" and "8" are clearly different, right? Well, sure they are... until CAPTCHAs start putting squiggly lines behind them to confuse automatic image readers. One of those squiggles could easily make it hard to tell the difference between the two numbers.

Squiggles can confuse other characters as well. Depending on placement and font, a "c" can look like an "o," an "o" look like an "a," and other characters can be hard to distinguish. 

If your CAPTCHA won't submit, take a close look to make sure that your eyes aren't being thrown off by background noise.

A Case of the Wrong Case

Some CAPTCHAs don't care if the letters you enter are upper or lowercase, but others are case-sensitive, meaning that your shift key might be the reason why your CAPTCHA isn't going through.

If the CAPTCHA shows both upper and lowercase letters, be sure to enter your characters exactly as displayed. If all of the letters have the same case, you might be able to enter it either way, but if your entry is rejected, try typing it exactly as it is shown.

6
When Case Sensitivity is Too Sensitive

Of course, case-sensitive captchas open the door for even more confused letters. For example, an uppercase "O" can look a lot like a lowercase "o" when letters are different sizes, and the same with "C" and "c."

If your CAPTCHA is being stubborn, try changing the case of letters that look the same in upper- and lower-case to see if it helps.

7
When the "Eyes" Don't Have It

One of the drawbacks of CAPTCHAs is that they are very difficult or impossible for people with vision impairments to use. To get around this problem, some sweepstakes offer an audio version of their captchas. If this is an option, try listening to a hard-to-enter code. Look for a small speaker symbol near the CAPTCHA to turn on audio mode. It's often easier to hear the code than to type it.

8
There's No Shame in Admitting Defeat

If you are having a lot of trouble with a CAPTCHA, you don't have to let it drive you crazy, just try reloading it to get a different code that might be easier to decipher. You can nearly always do this by reloading the page in your browser, and some entry forms also offer the option to click on the code or press a reload button to get an easier-to-read captcha.

Don't Get Frustrated!

When you enter sweepstakes, annoying CAPTCHAs are just one of the frustrations you might face. Remember, being a winner is a marathon, not a sprint. Be patient and persistent and the prizes will come!
