You get more cash offers when you don't have many rubies and vice versa.

The game is totally playable w/o buying anything. So whether or not it's worth it depends on how you play, if there are any items that would be particularly useful to you. (I see a lot of people on here who buy tools. Personally I don't go through too many tools but I can't TT so when I have rubies I mostly buy energy related stuff cuz I want to play longer.) And also how much you get the rubies for. If you get your items from special offers you'll might get a significantly better deal than at the store. But to estimate the value of rubies you might look at how many rubies whatever you want costs in the store and consider how much money that number of rubies would cost you with the ruby package you're looking at. If you're cool with the cash comparision then go ahead.
