In most cases, coins are added to your account immediately. If you do not see an increase in your coin balance immediately after the purchase, kindly close the app, remove it from the background applications, and relaunch. 

However, sometimes the (Apple/Google Play) store might take up to 24 hours to credit the purchase, though your account might have been charged immediately. If you do not see the coins are being credited even after 24 hours, kindly send us a support request at help@wynnnslot.com with the following details:

• Your Player ID
• Screenshot of the original receipt
• Purchased coin amount 
• Time of the transaction

But, we strongly recommend you wait for at least 24 hours before sending a support request.
