I thought that very inactive account will be deleted because my account has no activity at all since I created it but I'm surprised that I can login back.
LuckyDiamond doesn't have the dormant or inactive account related terms. That's why your account is still accessible. They may add such rules if it starts to cost a good amount to keep the old inactive user database on their server.
Maybe I'll deposit small amount later to check my luck, hopefully I'll get a better luck than you friend.

Since there is plinko game which is one of my favorite game to play, I'm going to test my luck in their plinko game.
I had made two more small deposits on that day after my post, and my total losing sum is
$200 now. I got nothing in return as my VIP level is 0 with the small wager. I have already said bye to this casino as I'm quite unlucky there. I wish you good luck if you want to try their games.
