&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Hackenbush is one of the simplest possible board games, used to show the connection between game theory and real numbers. This game involves players subtracting branches colored N or P to match the players (usually drawn as red or blue), or given no color (usually drawn in green). This game is interesting for the potential of green branches to generate a whole new line of numbers called the [https://en.wikipedia.org/wiki/Nimber nimbers] or [[E:Q5,38|star]] numbers.&lt;br /&gt;
