+
+Oh, hello! Funny seeing you here.
+
+I appreciate your enthusiasm, but you aren't going to find much down here.
+There certainly aren't clues to any of the puzzles. You do risk spoiling a few
+surprises for yourself, though. Best to play the normal way and discover
+everything as it was intended, I think. The best surprises don't even appear
+in the source until you unlock them for real.
+
+Please be careful with automated requests; I'm not Google, and I can only take
+so much traffic. Please be considerate so that everyone gets to play.
+
+If you're curious about how Advent of Code works, it's running on some custom
+Perl code. Other than a few integrations (auth, analytics, ads, social media),
+I built the whole thing myself, including the design, animations, prose, and
+all of the puzzles.
+
+The puzzles probably took the longest; the easiest ones were around 45 minutes
+each, but the harder ones took 2-3 hours, some even longer than that. A lot of
+effort went into building this thing - I hope you're enjoying playing it as
+much as I enjoyed making it for you!
+
+If you'd like to hang out, I'm @ericwastl on Twitter.

+<article class="day-desc"><h2>--- Day 20: Infinite Elves and Infinite Houses ---</h2><p>To keep the Elves busy, Santa has them deliver some presents <span title="This was before the Elves unionized, apparently.">by hand, door-to-door</span>. He sends them down a street with infinite houses numbered sequentially: <code>1</code>, <code>2</code>, <code>3</code>, <code>4</code>, <code>5</code>, and so on.</p>
+<p>Each Elf is assigned a number, too, and delivers presents to houses based on that number:</p>
+<ul>
+<li>The first Elf (number <code>1</code>) delivers presents to every house: <code>1</code>, <code>2</code>, <code>3</code>, <code>4</code>, <code>5</code>, ....</li>
+<li>The second Elf (number <code>2</code>) delivers presents to every second house: <code>2</code>, <code>4</code>, <code>6</code>, <code>8</code>, <code>10</code>, ....</li>
+<li>Elf number <code>3</code> delivers presents to every third house: <code>3</code>, <code>6</code>, <code>9</code>, <code>12</code>, <code>15</code>, ....</li>
+</ul>
+<p>There are infinitely many Elves, numbered starting with <code>1</code>. Each Elf delivers presents equal to <em>ten times</em> his or her number at each house.</p>
+<p>So, the first nine houses on the street end up like this:</p>
+<pre><code>House 1 got 10 presents.
+House 2 got 30 presents.
+House 3 got 40 presents.
+House 4 got 70 presents.
+House 5 got 60 presents.
+House 6 got 120 presents.
+House 7 got 80 presents.
+House 8 got 150 presents.
+House 9 got 130 presents.
+</code></pre>
+<p>The first house gets <code>10</code> presents: it is visited only by Elf <code>1</code>, which delivers <code>1 * 10 = 10</code> presents. The fourth house gets <code>70</code> presents, because it is visited by Elves <code>1</code>, <code>2</code>, and <code>4</code>, for a total of <code>10 + 20 + 40 = 70</code> presents.</p>
+<p>What is the <em>lowest house number</em> of the house to get at least as many presents as the number in your puzzle input?</p>
+</article>
+<p>Your puzzle answer was <code>776160</code>.</p><article class="day-desc"><h2>--- Part Two ---</h2><p>The Elves decide they don't want to visit an infinite number of houses. Instead, each Elf will stop after delivering presents to <code>50</code> houses. To make up for it, they decide to deliver presents equal to <em>eleven times</em> their number at each house.</p>
+<p>With these changes, what is the new <em>lowest house number</em> of the house to get at least as many presents as the number in your puzzle input?</p>
