		<h3>How It Works</h3>
		<div class="section">
			<p>
				Each Key increases your odds, but with <em>diminishing returns</em> — meaning each additional Key adds less benefit than the one before.
			</p>
			
			<p>The formula is:</p>

			<pre><code>% Chance Free = n / (n + 10)</code></pre>

			<p>
				Where <code>n</code> is number of Keys. <br> 
				This means even with infinite Keys, the chance can never exceed 100%.
			</p>

			<ul>
				<li>1 Key → 9.09%</li>
				<li>5 Keys → 33.33%</li>
				<li>10 Keys → 50%</li>
				<li>20 Keys → 66.67%</li>
				<li>30 Keys → 75%</li>
			</ul>
