Best Value for Doughnuts

If you think you're going to stick with this game for a while, it may be best to go with trying to increase your multiplier. It's a long term investment into the later part of the game. In this case I'd go with the Beach Hideaway just for the sake of the exceptional multiplier.

If you are unsure or a bit more casual about your gaming, curate a few nice buildings or characters to enjoy. Everyone has different tastes, but characters that are always top rated are Luann, Frink, Otto... some of the characters no Springfield should be without!
