I've tried the 10 minute version out a few times (and won). I would slightly disagree with the "scammy" slant that you are presenting, although I do agree 100% that it would be made a ton better by upgrading to a 'provably fair' system. It is a new thing, and I suspect they were probably waiting to see if it even caught on before spending significant effort to build a 'provably fair' system. Thanks for bringing attention to this and recommending how to make it better.

I think this app is adding huge value to the community. There is not much that can be done with SBD at the moment other than holding, or cashing out. This lotto now gives value to the SBD that you have, even if it is just a few cents that you made off a post :)
