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></comment>

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. Totally worth it, though!&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&amp;#x2F;kohctpyktop-engineer-of-the-people&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.zachtronics.com&amp;#x2F;kohctpyktop-engineer-of-the-peopl...&lt;/a&gt;</text></comment>
