Play any Mini Game with only 2,500 points earned:

Once you have earned the first 2,500 points in the game, save to memory. Now go to the Mini-games section. One there, you will see options to purchase one of the three mini-games Monkey Pool, Monkey Bowling or Monkey Golf. Each one costs 2,500 points.

The trick here is to remove your memory card from the machine at this point. Now you can select whichever mini game you'd like to play and it the game will not deduct the points from your earnings, as it won't be able to save. If you'd like to try a different mini game, simply reset Super Monkey Ball and repeat the process
