Show your receipt in store, charge the wheel, then send the result to Goodies on WhatsApp.
One spin per eligible receipt. Staff confirms the prize before pickup.
Staff checks the receipt, unlocks the wheel, then hands the phone to the customer.
After the wheel stops, staff redeems the prize right here.
Edit prizes on this staff phone. For now, spin settings are saved on this device, so use the same phone for the game unless we move this to Airtable/cloud later.
