-=== How to play Turtle in a Pond ===
-Did you know that:
-* You can load your own strategy for the turtle
-==== The Toolbars ====
-[[Image:TurtlePond_toolbar-1.png]]
-:from left to right
-# the Activity toolbar button (shown in the open position)
-# the New-game button
-# an area for messages
-# the Load-new-strategy button
-# the Reload-the-default-strategy button
-# the Activity stop button
-=== Strategy ===
-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.
-<pre>
-def _turtle_strategy(self, turtle):
-    c = turtle[1] % 2
-    for i in range(6):
-        col = turtle[0] + CIRCLE[c][i][0]
-        row = turtle[1] + CIRCLE[c][i][1]
-        if not self._dots[self._grid_to_dot((col, row))].type:
-            return [col, row]
-    return turtle
-</pre>
-In the '''default strategy''', the turtle choose a random direction and goes there if the dot is open.
-<pre>
-def _turtle_strategy(self, turtle):
-    c = turtle[1] % 2
-    n = int(uniform(0, 6))
-    for i in range(6):
-        col = turtle[0] + CIRCLE[c][(i + n) % 6][0]
-        row = turtle[1] + CIRCLE[c][(i + n) % 6][1]
-        if not self._dots[self._grid_to_dot((col, row))].type:
-            return [col, row]
-    return turtle
-</pre>
-In this strategy, the turtle will go off the edge if it can.
-<pre>
-def _turtle_strategy(self, turtle):
-    c = turtle[1] % 2
-    for i in range(6):
-        col = turtle[0] + CIRCLE[c][i][0]
-        row = turtle[1] + CIRCLE[c][i][1]
-        if self._dots[self._grid_to_dot((col, row))].type is None:
-            return [col, row]
-    n = int(uniform(0, 6))
-    for i in range(6):
-        col = turtle[0] + CIRCLE[c][(i + n) % 6][0]
-        row = turtle[1] + CIRCLE[c][(i + n) % 6][1]
-        if not self._dots[self._grid_to_dot((col, row))].type:
-            return [col, row]
-    return turtle
-</pre>
-The dots are stored in a 13x13 array. Each dot has an attribute, 'type', that determines it status. The edges have a type=None. Occupied dots have a type=True. Unoccupied dots have a type=False.
-Your strategy should start with:
- def _turtle_strategy(self, turtle):
-The turtle argument is a tuple containing the column and row of the current turtle position. That is, turtle[0] is the horizontal position and turtle[1] is the vertical position.
-Your strategy should return a tuple containing the column and row of the new turtle position, e.g.,
- return [col, row]
-There are some resources that you can use in your program, including:
-;CIRCLE: a 2x6x2 array of offsets that can used to find the column and row of the dots surrounding the turtle.
-;self._dots: the array of dots.
-;self._pressed: the index of the most recent dot pressed by the user
-;self._orientation:you can set the orientation of your turtle by assigning a number from 0-5 (clockwise beginning with 30 degrees from north)
-;self._set_label('your message here'):you can write a message on the toolbar if you want to communicate what your turtle is thinking
