Additionally, seasons contain various bonus contests, like the 'Viewer Submitted Opening Bonus'. </p><p>Prior to season 21, there was originally one tournament in each season. This tournament consisted of several qualifying stages and one "superfinal", and the winner of the superfinal is called the "TCEC Grand Champion" until the next season. Prior to season 11, the tournament used a cup format, while starting in Season 11, the tournament used a division system. Starting in season 13, there was also a cup tournament consisting of the top 32 engines in the main tournament, resulting in a 5-round single elimination tournament.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Engine_settings/characteristics"><span id="Engine_settings.2Fcharacteristics"></span>Engine settings/characteristics</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Top_Chess_Engine_Championship&action=edit&section=3" title="Edit section: Engine settings/characteristics"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Permanent_brain" title="Permanent brain">Pondering</a> is set to off.
