<p><strong>Puzzle Gate</strong> is a next-generation WordPress security plugin that replaces annoying traditional CAPTCHAs with an <strong>intelligent, interactive puzzle system</strong>. Unlike conventional image/text CAPTCHAs that rely on external services and frustrate users, Puzzle Gate offers a fast, self-hosted solution that’s both highly secure and surprisingly user-friendly.</p>
<h3><strong>Why Website Owners Choose Puzzle Gate:</strong></h3>
