Their is no option of deposit and if it is attached to the wallet then i think user have to check with the site reputation. About the game i think it still needs lot of work to be done.
Actually if you read just a few post above, you will see how to make a deposit. The problem is that its off-chain, meaning its not the usual route we used to see in other online casinos. I like the idea of using LN here but majority of players are not familiar to it might take time to sink in before actual players used this casino.
