Possible reasons you haven’t received the voice code are:
-You are using a phone number that is already associated with another LuckyLand Slots account. Only one phone number per account! :)
-You entered a phone number that is from a Voice Over IP service/website. We only accept phone numbers from standard consumer phone service carriers (Verizon, AT&T, T-Mobile, etc).
-Perhaps you put in your number incorrectly! Don’t worry, it happens! Just close out, and reopen your game and you can have another go of it :). You can try up to 3 times, and then there's a cool down time of 15 seconds to 5 minutes before you can try again.
