not going to give specifics, a vouch from dooglus especially should clear most doubts though.
I do hope dooglus vouch for this but all I know that it is impossible to have +EV. A good strategy will get you near to zero EV not make them +EV . Also that this is not clear, you mentioned that it works on a particular dice sites . It should works on any dice sites that have the same house edge since they are not different
it's not some betting strategy like Martingale, it's just that on this particular site, it is possible to get an edge.
