&lt;p&gt;&lt;strong&gt;Type of Dominoes Used:&lt;/strong&gt; Any Domino&lt;br /&gt;
&lt;strong&gt;Type of Game:&lt;/strong&gt; &lt;a href=&quot;/trump-and-trick-games&quot;&gt;Trump &amp;amp; Trick Game&lt;/a&gt;&lt;br /&gt;
&lt;strong&gt;Plunge is a BIDDING VARIATION for:&lt;/strong&gt; Forty-Two, Seventy-Nine, Eighty, or Eighty-Eight hand.&lt;br /&gt;
The tactic of bidding Plunge allows for communication between partners during bidding and start of play about the tiles they hold in their hand.&lt;/p&gt;

&lt;p&gt;&lt;br /&gt;
If Plunge is the winning bid, the bidder&amp;#39;s hand must contain at least four doubles and, by bidding Plunge, the bidder relays to his partner that he holds a great hand. The bid is automatically 168, and the bidder cannot lose a single trick. The bidder&amp;#39;s partner is required to declare trumps, based on his own hand, and to lead by playing the first tile of the first trick.&lt;br /&gt;
When a player bids Plunge, he is gambling that he holds the double in his hand to the trumps and offs that his partner has yet to declare. The bidder takes a huge risk by bidding Plunge. If he is lucky, he and his partner match each other on most of the doubles and offs suits; if not, the consequence of his bid is a huge loss.&lt;/p&gt;
