Having trouble hitting the ball up the outer left loop 4 times? Try this trick: Whenever the ball is initially released into the field(when a new ball is sent or your ball is saved), the ball will bounce up near the edge of the right flipper. While the ball is in limbo, shake the field left(Down on the D-Pad) 4 times; once while the ball is rising, once at the peak, and twice on the way down. Hit the ball with the right flipper as soon as it is in range(the tip of the flipper will strike the ball), and it will always go up the outer left loop. Finally, there's a use for the Ball Saver on the slots!

Another useful method is to stop the ball and hold it with the left flipper up. While the ball is still, it will spin counter-clockwise. Now, release and immediately hit the left flipper; the ball should roll a pixel or two down the flipper before shooting straight up the Evolution Lane. The timing is difficult, but with practice these two tricks will allow you to evolve pokemon at your leisure.
