Its the result of the Zachatronics formula having time to grow after SpaceChem.&lt;p&gt;The main reason I personally prefer Opus Magnum is that solving the levels is easy, but optimizing is challenging and rewarding. TIS-100 on the other hand has a higher difficulty to initially solve the puzzles and optimization becomes a little bit of a guessing game. Also having only 3 saved solutions per level makes it hard to optimize without losing past solutions.</text><parent_chain><item><author>AlEinstein</author><text>If you&amp;#x27;ve not heard of TIS-100 then, given that you&amp;#x27;re currently on a site called &amp;quot;Hacker News&amp;quot;, I heartily recommend it to you: &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&amp;#x2F;tis-100&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&amp;#x2F;tis-100&amp;#x2F;&lt;/a&gt;&lt;p&gt;Also excellent is Shenzhen IO: &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&amp;#x2F;shenzhen-io&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&amp;#x2F;shenzhen-io&amp;#x2F;&lt;/a&gt;&lt;p&gt;Also excellent is everything here: &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&lt;/a&gt;</text></item></parent_chain></comment><story><title>Zachtronics: Ten Years of Terrible Games (2017) [video]</title><url>https://www.youtube.com/watch?v=Df9pz_EmKhA</url></story>

Your job is to build ICs which conform to predefined stimulus&amp;#x2F;response patterns.&lt;p&gt;Unfortunately, it requires Flash, so it may be difficult to get to run in a browser nowadays.
