The Cupcake Boost instantly brings all customers to MAX Happiness! The cupcake can be found in the bottom left of the screen, with the number below indicating how many Cupcakes you currently have.
Tap on the Cupcake to apply the boost to all customers present on the screen, boosting their happiness to MAX.
If the Cupcake is grayed out, that means all Customers are at their MAX happiness!
A plus sign indicates you're all out of cupcakes but can purchase more for Gems! Tap on the plus sign once to see the cost, and again to confirm the purchase.
