Checked the website out and it looks decent for a beta version, but I have a doubt. Why does the website say that the house edge is 1% when it says 0.5% in this thread? Care to clear up the confusion op?
The difference of house edge claim (1% on site and 0.5% on this thread) has created doubt in my mind that house edge might be higher and OP is just showing house edge for advertisement purposes. It can be a typing mistake too but for a site of such a level, these mistakes creates unnecessary doubt about the authenticity of the gambling site.
The crash game itself is 1% house edge, 50% of this house edge ie. 0.5% goes directly into weekly challange pool and is 100% distributed to challanges winners, making it 0.5% effective house edge. The house will only profit 0.5% of total wagers on average.
