          <title>一筆 / Hitofude / Ippitsu Japanese puzzle game</title>
          <description>&lt;p&gt;一筆 (“Hitofude” = Single Stroke) aka “Ippitsu” is a puzzle game by H.Hirabayashi.&lt;/p&gt;

&lt;p&gt;Released in 1995, a decade before &lt;em&gt;Mitchell Corp&lt;/em&gt; &amp;amp; &lt;em&gt;Nintendo&lt;/em&gt;’s Polarium 直感ヒトフデ (“Chokkan Hitofude” = Intuitive Single Stroke) &amp;amp; Polarium Advance 通勤ヒトフデ (“Tsūkin Hitofude” = Commuting Single Stroke).&lt;/p&gt;

&lt;p&gt;As &lt;a href=&quot;/2014/01/01/polarium-advance-daily-puzzle-challenge&quot;&gt;huge fan of the Polarium games&lt;/a&gt; this discovery has rocked my world.&lt;/p&gt;

&lt;p&gt;You can read about it in &lt;a href=&quot;https://www.vector.co.jp/magazine/special/970912/sp7091211.html&quot;&gt;this 1997 feature at Vector&lt;/a&gt; and &lt;a href=&quot;https://www.vector.co.jp/soft/win31/game/se024209.html&quot;&gt;download it from its listing page&lt;/a&gt;. The author’s website is &lt;a href=&quot;https://web.archive.org/web/20030506062907/http://www.hiraba.com/slaveofpc/software/ippitsu/index.html&quot;&gt;archived in the Wayback Machine&lt;/a&gt;. It will run on Windows 3.x and Windows 95, at least. I’m running here in English Windows 95 through DOSbox-x.&lt;/p&gt;

          <title>Polarium Advance: Daily Puzzle Challenge</title>
          <description>&lt;p&gt;I started a new job at Apple in June 2013, and seeing as I was living away from home a fair bit I had a bit of free time and the hunger for a big puzzle game to get my teeth into. So I bought an extra copy of Polarium Advance. I’d played the game before but had never finished all of the puzzles.&lt;/p&gt;

&lt;p&gt;It’s a typically brilliant game by &lt;em&gt;&lt;a href=&quot;https://en.wikipedia.org/wiki/Mitchell_Corporation&quot;&gt;Mitchell Corporation&lt;/a&gt;&lt;/em&gt; which was &lt;a href=&quot;https://web.archive.org/web/20041204110943/http://www.nintendo.co.jp/nom/0412/pick/1_int/index.html&quot;&gt;in development for Game Boy Advance when Nintendo saw it&lt;/a&gt; and requested &lt;a href=&quot;https://en.wikipedia.org/wiki/Polarium&quot;&gt;a version for their new handheld: the Nintendo DS&lt;/a&gt;. After that version was released the team returned to &lt;a href=&quot;https://en.wikipedia.org/wiki/Polarium_Advance&quot;&gt;the GBA version&lt;/a&gt;, which probably explains why it’s a more fully featured and all round better game than the DS version.&lt;/p&gt;

&lt;p&gt;The game’s Daily Puzzle mode has 365 puzzles and I started playing them on &lt;a href=&quot;https://twitter.com/gingerbeardman/status/365553568012455936&quot;&gt;8th August 2013&lt;/a&gt;. I made quick progress: &lt;a href=&quot;https://twitter.com/gingerbeardman/status/367398889692737536&quot;&gt;by 13th August I’d done 87 puzzles&lt;/a&gt; and after a week I’d done more than one hundred. The half way point of puzzles was reached within two weeks! Things slowed down during September as the puzzles became more difficult.&lt;/p&gt;

&lt;p&gt;I’m writing this looking back and the first mention of finishing it by New Year was on &lt;a href=&quot;https://twitter.com/gingerbeardman/status/388766818770644992&quot;&gt;11th October 2013&lt;/a&gt;. But I have to think I’d considered before that point.&lt;/p&gt;

&lt;p&gt;Anyway, it was a &lt;a href=&quot;https://twitter.com/gingerbeardman/status/414923359588462593&quot;&gt;bit of a squeeze&lt;/a&gt; in between Christmas and New Year but &lt;a href=&quot;https://twitter.com/gingerbeardman/status/418107154793762817&quot;&gt;I managed it&lt;/a&gt;!&lt;/p&gt;

&lt;blockquote&gt;
