title: How to model simple generic 2 players game?
body: <p>I am pretty new to modelling (I'm 15). I am learning activity diagrams and use cases along with UML but I cannot figure out how to correctly model this situation:
  Player 1 makes a move
  Player 2 makes a move
  Game ends when player cannot move</p>
  
  <p>I designed a loop but it contains two GAME OVER decisions after each player move and it does not seems right to me.</p>
  
  <p>I have:</p>
  
  <pre><code>Player 1 -- &gt; MOVE -- &gt; MOVES AVAILABLE? Yes --&gt; GO TO Player 2, No -- GAME OVER
  Player 2- - &gt; MOVE -- &gt; MOVES AVAILABLE? Yes --&gt; GO TO Player 1, No -- GAME OVER
  </code></pre>
  
  <p>But I think I cannot place the GAME OVER evaulation elsewhere because it can happen after either player's turn. Am I on the right track?</p>
