Tips for winning sweepstakes game?

There is no active sweepstakes/contest at this time. If you mean winning the grand prize in this month's seasonal set, the Botanist's Quarters, you must buy enough seasonal set items to collect more than 2600 points (watering can symbol). Watering can points are shown above each item. Best to buy the most expensive items to save space. Some players collect pink star boxes from previous months, and open them only when the new set starts to get this month's Marvelous prizes, which will give points right away.
