Balloon Express unlocks after you rescue Foreman Gus. Once unlocked, you can complete balloon orders.
To begin a balloon order, tap on the Balloon Express platform, then tap Start. The first row of loading crates is displayed. Tap on a loading crate’s sign to see the number of items needed. If you have the required amount, tapping the Load button fills the crate. If you do not have enough, tapping the Load button allows you to purchase the remaining items needed using gems.
Once you’ve filled a row of crates for the balloon, the balloon takes off. For every row of crates filled, you earn rewards. Fill all three rows before time runs out for maximum rewards.
Balloon Express runs on a tight schedule - upon opening the first order, the timer begins a countdown to final balloon lift off. Any orders that have not been completed before the timer reaches 0 will reset when the balloons return after their deliveries. When all the balloons are in the air, the time until they return is displayed on the timer. You can opt to speed up the balloons’ return by using gems.
