Let's keep it simple.

We know just how good our games are - we've put all our time, skill and creativity into making them as involving and memorable as they can be. And that's why we have the confidence to offer this starkly simple guarantee:

If you are dissatisfied with one of our games, simply let us know within 30 days of purchasing your registration that you would like your money back... and you'll get it.

We won't even insist on your telling us why (though of course we'd prefer to know). For your part, all you have to do is uninstall the registered game from your system and we're all square.
