You must gamble an equivalent amount of diamonds or more, to the amount of diamonds you are withdrawing. The 'gambling count' start from the moment you deposit. Gambling on Free diamonds don't count for this. For example, if you are withdrawing 5000 diamonds, you must have played with at least 5000 diamonds (easy!)
Some withdrawals need manual admin approval. If this is the case, don't panic. After the admin's approval, simply go to the shop again, where you will see a button to take your items. Feel free contact admin in our Discord if you need any withdrawal help.
