An awesome Club Penguin cheat and glitch has been found that will allow you to earn free coins easily! To do this you must have an iPad and download the free My Penguin app.
Step 1. Open the My Penguin app on your iPad. Choose and play any game.
Step 2. At the end of the game it will tell you how many coins you have earned. DO NOT PRESS "OK", instead click the home button on your iPad.
Step 3. Open up the My Penguin app again.
Step 4. It will ask you if you want to quit. Click "Yes" (this screen may take a few seconds to show).
Step 5. Again, click the home bottom on your iPad. Then open the app again. Then click "Yes" again. Every time you repeat this process, you add more and more coins to your account without having to play the game over.
Look at how many coins I earned when I repeated this process for about 20 times:
Once you have repeated this process a couple of times, take a look at your coins - they should have added up pretty high! You can do this trick to earn yourself up to one million coins!
