you are right the offers are only to get you to buy something.When they ask for your phone number they want to charge you a monthly service for ringtones or some monthly service they provide. you are also right about having a credit card, it's a catch to hook you into buying something you don't want for credits. There should be an easy way to get credits,other than those offers. It sucks. I like playing here,I've made some very nice friends here,but until I get more points,I'll be playing somewhere eles.I ,can't afford to buy credits and if I could I would just play for real cash.
