gamblers have not interested it..Just to settle this, we are not changing to zero-confirmation mode anytime soon. It is senseless for us to risk being doublespent against to the tune of 50BTC for the convenience of a player that wishes to gamble 0.002 BTC.
Zero confirm acceptance is unsafe for merchants, and has been for years (since transaction volume exceeded block capacity).
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.
