In this event, Stella will show up with her shop and have fantastic items for sale! While the event is active, cherries will appear in levels. Use boosters or make matches next to cherries to collect them. You only keep the cherries you've collected when you successfully complete a level!
You can then trade in cherries at Stella's Store for the different items she has available. If you purchase all the items in the store, Stella will give you an extra bonus for being a loyal customer!
The event ends after the timer has run out, or after buying all the items in the shop, whichever comes first. If the timer runs out, you will have one last opportunity to trade in any remaining cherries before the event ends.
