-<p>TODO</p>
+<p>
+  Only moves ending in the Arena zone (where no piece stand initially)
+  are allowed. If starting from inside the Arena, then a move must capture
+  something.
+</p>
+
+<ul>
+  <li>King and queen move like a queen restricted to 3 squares.</li>
+  <li>Pawns can capture backwards.</li>
+</ul>
+
+<p>
+  The first player who cannot make a move loses.
+  A player who lose both king and queen also lose the game.
+</p>
