The default strategy is simple: choose a random direction and go there if the dot is open.
In this strategy, the turtle moves down, regardless of whether the dot is open.
<pre>
def _turtle_strategy(self, turtle):
    turtle[1] +=1
    return turtle
</pre>
 
In this strategy, the turtle moves down until it is blocked.
<pre>
def _turtle_strategy(self, turtle):
    if not self._dots[self._grid_to_dot((turtle[0], turtle[1]+1))].type:
      turtle[1] +=1
    return turtle
</pre>
 
In this strategy, the turtle searches for an open dot, looking clockwise.

def _turtle_strategy(self, turtle):
def _turtle_strategy(self, turtle):
     c = turtle[1] % 2
     c = turtle[1] % 2

     for i in range(6):
     for i in range(6):
         col = turtle[0] + CIRCLE[c][(i + n) % 6][0]
         col = turtle[0] + CIRCLE[c][i][0]
         row = turtle[1] + CIRCLE[c][(i + n) % 6][1]
         row = turtle[1] + CIRCLE[c][i][1]

In this version, the turtle moves down, regardless of whether the dot is open.
In the '''default strategy''', the turtle choose a random direction and goes there if the dot is open.

In this version, the turtle moves down until it is blocked.
In this strategy, the turtle will go off the edge if it can.
