You might need to figure out something else like a deposits system, so the players don't have to wait for each rolls and pay the miners for transaction fee.
Announcing or updating a game with a deposit system has nothing to do with it (if you are talking against Luckyb.it being in safe mode or not rolling at zero confirmations). The decision lies with the gambling site whether to accept deposit/roll at zero confirmation or with confirmation. So wheth
I guess why they are not allowing such kind of transaction is already explained here:
Zero confirm acceptance is unsafe for merchants, and has been for years (since transaction volume exceeded block capacity).
and I think that is fair as zero confirmation/roll would open gates for double-spenders which will result to loss of gambling site accepting such kind of deposits/transactions.
