All CAPTCHA Types in BotBlocker: Maximum Flexibility and Reliable Protection

Bots and scripts are getting smarter, but advanced verification systems can stop even the most sophisticated attacks. BotBlocker includes a wide range of CAPTCHA options—customizable and combinable for the perfect balance of security and user experience.

What CAPTCHA Types Are Available in BotBlocker?

1. “I am not a robot” Button

The classic, minimalist approach: the user simply clicks “I am not a robot.” Perfect for reducing user friction and blocking the simplest bots.

2. “I am not a robot” Button + Google reCAPTCHA v2

Double-layer protection. After clicking “I am not a robot,” Google reCAPTCHA v2 is triggered—classic checkbox with additional Google challenges if needed.

3. Colored Buttons

The user sees several colored buttons and must click the one of a specified color (“Click the green button”). Colors and button placement change each time, making automation much harder.4. Animal Image Sets

A series of animal images appear, and the user is asked to select, for example, “all cats” or “the dog.” Visual logic is intuitive for humans but tough for bots.

5. Floating Colored Shapes

Animated colored shapes move across the screen. The user must click a shape of a specific color or form. Lively animation blocks simple bot recognition.

6. Floating Math Expression

A simple math problem (like “3 + 7”) appears on a floating background or among moving objects. The user enters the answer to pass the check.

Can You Use Multiple CAPTCHAs at Once?

Yes!
BotBlocker lets you combine any of its visual/interactive CAPTCHAs with Google reCAPTCHA v3.
This means: a user first solves a visible BotBlocker CAPTCHA, and at the same time, their behavior is silently analyzed by reCAPTCHA v3 (which assigns a risk score in the background).

Such layered protection blocks even advanced bots without disrupting the experience for real users.

When to Choose Each CAPTCHA?

  • “I am not a robot” Button: For maximum user convenience and frequent checks.
  • Button + reCAPTCHA v2: For a familiar, trusted Google solution.
  • Colored buttons, animal images, shapes: Best for blocking script-based and “smart” bots.
  • Math expressions: Great for sites with large audiences—quickly stops both automated and manual spam.
  • Combined with reCAPTCHA v3: The gold standard for high security with no usability loss.
